Using both jdk 1.6 and jdk 1.7 for different projects in Eclipse
This can be done for an Eclipse Run Configuration. You may define multiple such configurations, each of which will reference a "main class" in one of your projects. In Window -> Preferences -> Java -> Installed JREs define a location for each JRE/JDK. For a given Eclipse project: right click on the project, select Properties -> Java Compiler, override and set compiliance level settings. Check Use compliance from ..., visit the Java Build Path and be sure you have a JRE Library set that matches the desired compliance level. For a given Eclipse Run Configuration: Run -> Run Configurations... -> Java Application, select an old or create a new configuration, select the JRE tab and specify the Runtime JRE.

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, self-contained "units".

importing maven projects into eclipse
You need to install the svn client first on your windows machine. svn is a code control tool, using which you can connect to a code repository to checkout or checkin the code. You can download svn client from here: http://tortoisesvn.tigris.org/ Once you checkout the code/project, then you can import in eclipse. If it is a maven project then you should have maven eclipse plugin(m2e) installed. Follow this link to install m2e eclipse plugin: http://maven.apache.org/eclipse-plugin.html

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It could be that some of the files are just out of date.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 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 project 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 this for more information on .project file http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fmisc%2Fproject_description_file.html 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: <attributes> <attribute name="javadoc_location" value="jar:file:/path/to/javadoc.jar!/"/> </attributes> Mass replace the plain <classpathentry> with the enhanced one; DON'T FORGET TO BACK THINGS UP BEFORE DOING THIS :)

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 manually: http://help.eclipse.org/juno/topic/org.eclipse.jdt.doc.user/reference/preferences/java/buildpath/ref-preferences-classpath-variables.htm?cp=1_4_2_0_1_0 . 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 much cleaner. 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.

How to maintain JAVA projects irrespective of IDE (Netbeans and Eclipse)
Use a common build infrastructure, like maven. This encapsulates (as good as) all settings inside the maven pom.xml files (source encoding, java version etc.). Also versioned library dependencies, subprojects are managed in maven. NetBeans knows maven out-of-the-box, and eclipse has a good maven plugin. In my experience manual configuration, especially in eclipse, and grown ant scripts, are cumbersome.

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

Eclipse indexer proper c++11 syntax highlighting when generating projects with cmake
The answer is pretty simple. The eclipse cdt generator ignores the definitions added with add_definitions(...) when parsing the symbols. Instead it uses the CMAKE_CXX_COMPILER_ARG1. So all you have to do is: Add -DCMAKE_CXX_COMPILER_ARG1=-std=c++11 when invoking cmake Generating project files from commandline: cmake ../../src -G"Eclipse CDT4 - MinGW Makefiles" -DCMAKE_ECLIPSE_VERSION=4.2 -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER_ARG1=-std=c++11 Generating projects from cmake gui: - Select source and build directory. - now BEFORE hitting configure or generate. Press "Add Entry" and add a new entry. Name:CMAKE_CXX_COMPILER_ARG1 Type:STRING Value:-std=c++11 - press Generate and create the Eclipse project It is important to set the CMAKE_CXX_COMPILER_ARG1 upfront before hitting c

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 Android. 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. Build Initialization feature is in progress: http

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: [submodule "volley"] 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. [Update] For library projects that you don't need to modify its source, you ca
