|Commit several projects in Eclipse SVN|
You can only commit them together if they are all part of the same working
copy. If you checked each project out individually via Eclipse, this will
not be the case.
Unless there's very tight coupling between the projects, you normally
should not be committing multiple projects at once. It's not about making
things less convenient to you, but about making your commits smaller,

|Eclipse Maven Projects False Error|
It could be that some of the files are just out of date. When I get this I
do a refresh of the affected projects and then clean the workspace (Project
-> Clean...) cleaning all projects.
If the refresh and clean don't do the trick, then I'd suspect that your
maven settings in Eclipse point to a different set of repositories than
does the command line maven's settings.xml. Go into the maven property
page in Eclipse preferences and confirm that you're using the same
settings.xml (re-select just to be sure).
|How properly import maven projects to eclipse?|
I guess there might be some workspace issue. You might have checked out the
project in workspace itself(not sure so pardon for that).
What you can do is, try checking out your project in some other drive and
then import the parent project. You will again see all POMs aligned in
hierarchical way and then i suppose, you won't be asked for entering name
for parent project and this will do the trick.
|Deploying libraries in Web Fragment projects in Eclipse|
I have just found a two step answer to my question.
In the scenario #1 above after doing it you have to go the Web Fragment
project properties and then go to Deployment Assembly, press the "Add"
button, select Java Build Path Entries and select all the libraries you
want to be included in the WEB-INF/lib directory of the server.
Once this is done the libraries selected will be copied to the WEB-INF/lib
when publishing the server or exporting the war.
|Eclipse not finding libgdx projects to import them|
Eclipse need .project file to import the projects into workspace. what you
can do is create a new project and copy the source and libraries into that
Alternative method can be that create a new project and copy the .project
file from that project to your project but make sure you edit the .project
file and change the name of that project according to your project. read

I will suggest you to use the First method .
|How do I change an external JAR for multiple Eclipse projects at once?|
I dont't know a way, but can tell a hack:
Open some of your .classpath files (in the root of each project). They
probably all contain a <classpathentry> related to your JAR. Add the
Javadoc location to one and check the change in the <classpathentry>;
it will be something like:
Mass replace the plain <classpathentry> with the enhanced one; DON'T

|How to harmonize Eclipse projects between Windows and Ubuntu?|
Did you add the jar to the library as an external jar? That would be the
path it stores, then. Use a variable instead if you have to add it
. It's possible, though, that if this is part of Java 7, you just need the
latest version of Eclipse--it supports Java 7 explicitly.
|Should projects be divided into separate Eclipse IDE workspaces?|
Separate workspaces. If you want to copy workspace properties, you have
that option in Eclipse. I even keep branches in separate workspaces. It's
example reason: Different target platforms for each project. It would be
incomfortable to constantly switch target platforms from the preferences.
Conclusion: It seems more appropriate to have 2 opened Eclipses, than
confusing working sets.
|issues with Eclipse and references on Android projects|
How is that even possible?
I haven't run into it as a problem in quite some time, but the compiled
version of your resources apparently got out of sync with the compiled
versions of the Java classes referencing those resources. Project > Clean
from the Eclipse main menu solves this.
Make sure you are on a relatively recent version of the ADT plugin for
Eclipse (current version: R22).

|How to export an Eclipse builder (or package it) for Importing to other projects?|
If you've implemented the builder using the New>Program sequence adding
the program you're calling in that manner, then the simplest solution is
use the same specifications and add an external tool configuration with the
same definition (you may need to delete the definition from the original
project builder tab).
Once defined as an external tool, the tool can be imported using the import
menu on the project builder tab.

|Practice for ensuring Android projects build right after SVN checkout in Eclipse|
There is nothing special about the libraries that the ADK adds to the class
path. If you want to be able to check in all of your project's
dependencies, you can copy the referenced jars to a local directory and
then point the class path to those instead of using the provided library
groups. Because the android plugin has that new wacky system that
automatically adds stuff in the libs directory to your path and to your
apk, I wouldn't recommend putting these other jars in there. Normally what
we'll do here is create a separate folder in svn named third-party or
something like that, and then use svn:externals to reference the necessary
jars. Having one common place to store third-party jars makes versioning
and configuration management easier.
To illustrate things a little more clearly, th

That should place that project on Tomcat's classpath.

|How to use Gradle to generate Eclipse and Intellij project files for Android projects|
Gradle itself is a generic build tool, it is not created specifically for
All the functionality is enabled using plug-ins. Traditionally, build
plug-ins don't generate project structure. That's the job of project
specific tools. The android plug-in for Gradle follows this.
The problem is that current android tool in SDK generates old type of
project structure (ant builds). The new project structure can only be
generated via Android Studio.
There is a concept of archetypes in tools like Maven, which allow using
project templates. Gradle does not support that yet (requests have been
made for this feature).
Refer to this thread: http://issues.gradle.org/browse/GRADLE-1289 , some
users have provided scripts to generate structure.

|Is it possible to share library projects between projects when using Android Studio and gradle?|
Couldn't you use git with submodules? e.g. In your .gitmodules file, you
may add this:
path = volley
url = https://path/to/volley/repository
You can set the url to Volley's official repository, or to your own
in-house version of volley. Other projects can be setup the same way and
point to the same volley repository.
I think this way, other users can call git clone and all the dependent
projects will be downloaded within the main project folder and they don't
have to worry about downloading the library projects separately.
For Volley though, I would just compile it into a JAR file and stick it
into the /libs folder of the main project. That is, if you don't need to
modify its source.
For library projects that you don't need to modify its source, you ca
