|Eclipse Kepler Java 8|
Have a look at this bug report from time to time for progress on Java 8 in
EDIT: For Kepler you need SR2 (4.3.2) and the Java 8 feature patch.
Starting with I20140318-0830 all Luna (4.4) builds contain support for Java
8 "out-of-the-box". The final version of Eclipse Luna (4.4) will be
released at the end of June 2014.
|Ant not working in Eclipse Kepler (Java Virtual Machine Launcher - A Java Exception has occured)|
Possible that Eclipse does not have the correct JAR defined. Did you try
to add the tools.jar needed for Ant?

|No "JavaEE" perspective even after installing Web,XML,... in "Eclipse-for Java Developers edition"|
Unless you have a reason to stay on Indigo, you could just download and
install the Juno version of "Eclipse IDE for Java EE Developers"
Keep your existing workspace (make a backup of it if you want). Install
eclipse (unzip). Start eclipse and point it to your existing workspace.
If you installed plugins for eclipse Indigo, you will need to install them
again for the Juno version.
|setup maven project for java ee 7 (full profile) with eclipse (kepler-ee) and git|
You can use EGit (an Eclipse Git plugin) as a complement for the most
common tasks. I used it a few years ago, had some issues, but the guys
developed it quite actively so it should be mature for now.
As for Maven + Glassfish, I'd recommend reading a few tutorials like Maven
in 5 minutes and this for setting up the devenv. Believe me, there are tons
of tutorials out there.
|Error when installing "Maven Integration for Eclipse (Juno and newer)" in Eclipse Kepler|
If you downloaded the EE version, then the m2e is already installed along
with the IDE.
On another note, with concise question content and proper formatting, your
question is allowed.
|how come an Eclipse plugin that targets Eclipse version 3.5 works with Juno but not Indigo or Kepler?|
The <?eclipse version="3.5"?> tag in plugin.xml file does not
specifies what version of Eclipse you want to target. It just specifies the
version of plugin.xml syntax that you wish to use. Newer versions of
Eclipse will support old syntax, but not the other way around.
What really controls the version of Eclipse that your plugin supports are
the dependencies specified in plugin MANIFEST.MF files and feature
dependencies in feature.xml files. A common problem is being unable to meet
the version constraint specified in one of those dependencies.
The trouble with using dropins folder installation method is that you don't
see the problem that documents why your plugin could not be activated.
Instead, use the "install additional software" wizard in Eclipse and you
will see the issue whe
|Eclipse Kepler startup error "NoClassDefFoundError: org/eclipse/swt/widgets/Display"|
Go to the properties of your eclipse shortcut and add a -clean parameter.

|Eclipse upgrade juno to kepler. Eclipse wont start|
If we have eclipse.ini
Kelpler will crash on start. Juno is working with this settings.
But when we have lower eclipse.ini. Eclipse is starting.
The only problem left is to how force Kepler to dont crash -Xms bigger
(I have 8gb of ram)
And 512m is to small for me to build workspace :/
EDIT Solution is also increase Xmx to 2048
|Eclipse: How to install uml2 Tools SDK in Eclipse 4.3 (kepler)?|
Just installed this today....

Then hit the Next button to install....
|Eclipse Juno Perspective tool bar|
There are two things you can try:
Reset your current perspective (Window/Reset perspective...). Although your
configured set of views will get lost, it might bring back the perspective
If that does not work, then you should reset the entire saved workbench
GUI. This can be done by deleting the
.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi file from your
workspace folder, or by starting eclipse with the -clearPersistedState
Point 2. assumes, that in case of Juno you are using Eclipse 4.2 (the new
GUI, not 3.8, the old).
|Reset Eclipse perspective layout|
From the image provided you do indeed have a minimized perspective
stack...it's the far right toolbar at the top of the image that has just
the icons for the java and debug perspectives. If you click on its
'restore' button the actual perspective will re-appear.
What it looks like is that you have the 'Welcome' (Intro) screen up and
maximized (thus the minimized perspective stack). If you were to click the
selected item in that top right toolbar the 'fly out' perspective would go
away allowing access to the view's restore (un-maximize) button.
Not sure why the Intro's blank though...;-)

Use the Kepler site. The URL you're using is not supposed to be used any
more (the timestamps you see are very old).

I don't think this is a good idea.
|How to configure solr4 with eclipse Kepler?|

you need to run solr in eclipse.
|M2e tool error for EClipse Kepler|
If you look at the m2e-wtp site you'll find that this feature is installed
by default in the Eclipse Kepler distribution. So it's not removed, but
just already included in the installation. Moreover, they (finally)
upgraded it from incubation to 1.0 version. Enjoy it!
m2e-wtp graduated from the Eclipse incubator to reach version 1.0.0.
Moreover, m2e-wtp and m2e are now included in the Eclipse Java EE
distribution by default. m2e-wtp 1.0.0 adds Java EE 7 support in Kepler and
a few other new cool features.
|Tomcat 7 won't start on eclipse Kepler|
Run netstat -aon and look for ports 8080 or 8005 and kill the process with

kill (pid of process)
Then just restart the server
|Eclipse CDT Kepler does not allow "Display as array..."|
Dive a bit deeper into the structure of the std::vector variable, and look
for s.th. named _M_start or alike (may be implementation dependent).
Cast this one to the final type array you know and want to see.
The reason is, that std::vector<T> just wraps and manages an array of
T internally and thus can't be displayed as an array itself.
|Is there a way to fix the "Close All" functionality on Eclipse Kepler?|
There are a couple of things you can try. The first step is the error log
(Windows -> Show View -> Error Log).
If you can't see anything in the log, you may try to start Eclipse with
java instead of javaw. Just add
to eclipse.ini. Maybe it prints something useful to stdout.
If that also doesn't help, try closing one window manually (for example
with Ctrl+W) and then "Close All" again. Repeat until it works. That might
give you a clue which window prevents Eclipse from closing everything.
If that doesn't help: You can also close windows by opening the window list
(Ctrl+E). Instead of search, go down once (so the selection is in the
list). You can now close windows using Delete (key repeat works but the UI
|Eclipse Juno/Kepler crashes|
1) If different Eclipse versions have the same problem, than it is problem
of your PC configuration and not of Eclipse. Have you tried to do the same
on other PC?
2) For your PC the problem may be old version of Java, e.g. Java 7 less
than update 12.
3) Maybe current user setting were corrupted, try to login as different
4) Review /workspace/.metadata/.log for analysis.

|How to create dynamic web project in eclipse kepler?|
You need to make sure that you download the package that contains these
tools. The one you want is labeled "Eclipse IDE for Java EE Developers".
This package supports dynamic web projects and has an editor for jsp files.
|Eclipse (Kepler) Ignoring Context Root|
If you're running your server from inside Eclipse, try right-clicking the
project and going to Properties > Web Project Settings. Change the context
root to what you want it to be and click Apply. Then in the servers tab,
turn off Glassfish if it's running, then right click your Glassfish server
and choose to clean it. Then try running your project.
|Cannot search for artifact in Eclipse Kepler using m2e plugin|
Very strange but now it worked using the following way:
Add some dependency directly in the pom.xml
Save the pom.xml to trigger the change. Now the library added directly
appears in the project.
Now I also got messages in the status bar like "indexing... " and
I am now able to add an dependency using the method from the question. It
now retrieves a list of artifacts of which I can choose.
Maybe a bug as also the add dialog should trigger the first repository
The information: "Artifact Id cannot be empty" still appears and had
nothing to do with the problem.

After that, in your eclipse project you can use the new configured jre

Hope this helps.
|Eclipse Kepler local javadoc confguration|
There does not seem to be an answer, and considering the installation is
plain vanilla it may indeed be a bug.
As a workaround, in order to solve this problem, I created an IIS virtual
directory with the jdk's api directory, registered the url for the Eclipse
javadocs and now it works.
|Can I deploy to and debug on Glassfish v2 using Eclipse Kepler?|
No. You will need to stay with Juno until you are able to move to a newer
version of GlassFish. The last version with GlassFish v2 support is
available at the following location:
|Error 404/resource is not available in Eclipse EE Kepler with Tomcat 7|
Is the context root setting for the project included in your URL? By
default, the context root is usually set to the project name (which may not
be what you expect).
You can change the context root by opening the project settings, selecting
"Web Project Settings", and adjusting the context root to suit your needs:
Whatever you use, it must match the context root used in your URL:
To set the context root to ROOT, just use "/".
You can also change the context root on the server's "Web Modules"
properties page. Open the "Servers" view (the same view used to stop and
start the server) and double-click the server with your web app. Click the
"Modules" tab (in the lower-left corner), then locate your application in
the list. You can change your deployment path after clicking the "Edit...
|use c++11 on mac os x mountain lion with eclipse (Juno or Kepler)|
Well after trying different things and expending tedious time fixing my
issue I will answer my own question with the hope someone with my same
needs will not experiment such annoying situation.
First as in a lot of forums remark and is well know the gcc compiler
provided for the Mac OS is old and obsolete (more than 5 years old is a lot
in computing terms), so first step to work with c++11 is to get a new
version of the gcc.
There are two options with the packets common managers (homebrew and
macports), I have to say that I was that frustrated that i tried both to
see if was a problem of the version in the packet manager even thought
should be the same, but for my surprise there is a small difference which
later I will explain, which bring me to suggest use macport because with
|Error in xCore file in Eclipse 4.3(Kepler)|
The error is caused mainly due to incompatible dependencies and version
mismatches. The following setting should fix your problem:
Firstly try doing a clean build. Generally that would solve your problem.
But if it doesn't try the following:
emf-xcore-SDK-VERSION and the following dependencies:
in the JAR's manifest file and rebuild.
EDIT: Turns out that the official documentation of xcore states to use
either Eclipse 4.2 or 3.8. Also the first version of Xcore will be part of
the Juno release train and is currently available in the Juno p2
repository. Maybe the subsequent versions will add Kepler build as well.
|How to manually install JAutodoc in eclipse kepler?|
Follow these steps for Installation:
Download jautodoc_1.11.0.zip file from :
Unzip the jautodoc_1.11.0.zip file from the eclipse folder.
Verify the following files get copied:
Plugin folder :
Features folder :
The JAutodoc feature should be available in Windows --> Preferences
Select the whole file or method or attribute --> Rightclick --> Add Javadoc

|Enabling C++11 in Eclipse Juno/Kepler/Luna CDT|
There's two things you have to do, first you need to setup your compiler,
then you need to setup CDT's language processor. Since you didn't mention
which compiler you're using, I'll assume it's GCC but the steps will be
similar for other compilers. (Note that you need a compiler that supports
C++11, of course.)
Setting up the compiler is fairly straightforward:
Right click your project and click Properties
Under C/C++ Build click Settings
Under GCC C++ Compiler, click Miscellaneous
In the Other Flags box, append "-std=c++11" to the list of tokens.
Click Apply and OK
At this point you should be able to rebuild your project and get it to run.
But CDT still may show errors for C++11 includes. Here's how you can
Right click your project and click Properties
|How to migrate eclipse Juno workspace to Kepler?|
It basically depends on the plugins used by the projects in your workspace.
If you use a standard Eclipse configuration there shouldn't be any problem,
just open workspace, close all projects and open them again. If it doesn't
work try cleaning them up.
|Glassfish Server Library not available in Eclipse Kepler?|
Looks like a bug in Eclipse Kepler / Glassfish Server Tools.
You can try the following:
Add this in your projects .classpath file:
<attribute name="owner.project.facets" value="jst.web"/>
Update the file
look like this:
<?xml version="1.0" encoding="UTF-8"?>
<runtime name="GlassFish 3.1"/> <-- Insert the name of your
Glassfish Runtime in Eclipse here
<installed facet="java" version="1.7"/>
|Problems integrating Maven with Eclipse Kepler|
Most convenient option:
The reason you're getting that error is because that repo is deprecated,
and it has been moved. Example of how the new repo looks:
Copy that in the Install New Software view, and you will see that it works.
Install the Maven Integration from Eclipse Marketplace (Help -> Eclipse
Download the EE version of Kepler (comes with m2e)
Choose your own release (bottom of the page) and use the Install New
|Eclipse Kepler not connecting to internet via proxy|
Did you make sure that you selected the "Manual" mode in the "Active

again and change that if it is not. I think that part is kind a buggy.
|Equivalent JVM options with Oracle J2SE 1.7, for Eclipse 'kepler' 4.3|
I'm running into the same thing. I think it's more a "what's deprecated in
your Java version" issue since it's passing most of the commands to Java.
The kepler help file doesn't get to specific with a lot of the commands you
and I are passing so that's what I'm thinking.
this is the Kepler help file
one thing I will say is after speed reading the Interweb I think these 2
can't be used at the same time but I dunno.
