Using Eclipse Dali as standalone tool
Currently, Dali does not provide support for validating your JPA configuration outside of an Eclipse workspace. (Dali has lots of dependencies on other Eclipse plug-ins.) That's a good idea, though. Perhaps you could submit an enhancement request via Eclipse's Bugzilla[1]. That said, you could use EclipseLink's Integrity Checker to validate your settings against a live database. See these links: [2] and [3]. If you are using another JPA implementation, it is possible it also provides a way to perform validation.

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

Opening source code instead of decompiled class in eclipse 3.5 and jd-eclipse plugin
In this blog post, the author describes two problems the jd-eclipse plugin has: The generated source code doesn’t line up with the debug line numbers because the generated code can’t include the original comments. If you choose to associate the “*.class” file type within Eclipse with the “Class File Editor” then you always get decompiled output even if you have real source attached. I guess 2. is the problem you are facing and it appears that jd-eclipse is not capable of what you need. It looks like the Mchr3k - JDEclipse-Realign might help you here. (I am not sure if it is available for your eclipse version though. Time to get an updated Eclipse perhaps...)

Tycho and Eclipse: How to resolve OSGI dependencies to my own bundles at development time within Eclipse, without opening all of them in the IDE
As indicated by Nick Wilson, you will need to install the m2e Tycho Configurator, which basically "links up" Eclipse and Tycho (i.e., makes Tycho available in Eclipse). You should've been pointed towards it after having installed m2e, but you can also install it manually: Go to Window > Preferences > Maven > Discovery. Click the "Open Catalog" button. This will open the "m2e Marketplace" window. Search for "tycho", this should give you the "Tycho Configurator" as sole search result. Click "Finish", you're done. I've had this issue as well, and it isn't simple to find the solution, so I hope this helps!

What's the use of the configuration in classpath for Eclipse project: "org.eclipse.jdt.junit.JUNIT_CONTAINER/4"
Your project needs to use JUnit libraries to run JUnit tests. The entry in CLASSPATH specifies the location of these libraries; in this case it's JUnit 4 from Eclipse. You can use some other version (3, for example) or libraries which are not part of Eclipse. To add this library you can use Eclipse UI. Open project properties, go to Java Build Path, then open Libraries tab. Then click Add Library, you'll get a list of libraries where you can choose JUnit. You have to do it every time you create a new project with JUnit tests.

I used m2eclipse plugins in eclipse.why the imported package still cannot be resolved by eclipse?
First of all, you're not using the m2e plugin; while it may be installed, it's not activated for this project: There is no little "M" on the project's icon The classpath doesn't include an entry org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER From what I can see, Eclipse can't resolve the dependencies since the variable M2_REPO isn't defined (if it could, you would see the absolute path to the JARs in the upper image after the symbolic path). To fix this, go to Preferences and search for "Classpath Variables". Add M2_REPO there with the correct path (default is $HOME/.m2/repository). If it already exists, make sure the path is correct. Alternatively, right click on project and select "Convert to Maven Project" under "Configuration".

org.eclipse.core dependency to org.eclipse.runtime suddenly changed
The problem is likely caused by version ranges. These ranges do not even have to be used for the Eclipse artifacts. Assume you depend on [1,2) and 1.1, and 1.2 are available. At a moment in time, 1.3 is added that has different dependencies. If it finds multiple groupId:artifactId with a different version then it picks the first it finds. Maven follows a breadth first strategy to find dependencies so that you can override it in your top level pom. This is of course very obscure and error prone. A better way is to specify all your app dependencies in one pom so you can ensure valid versions.

mvn eclipse:eclipse versus regular maven build
When you import an existing Maven project, it is done by m2e, the official Eclipse Maven plugin (when I say official I mean it is in the Eclipse incubation process). It offers more features and can be more convenient to use in my experience When you do it by eclipse:eclipse, it is done by a Maven Eclipse mojo which creates a simple Java project. The problem is that you have to re-do this again every time you change your pom. With m2e, this is usually done automatically.

My source folders are deleted after executing mvn eclipse:eclipse
I'm not sure what you are doing exactly but the eclipse plugin handles only eclipse configuration and does not touch any source folders. If the source folders are removed from your eclipse project, then the project/pom file is not set up correctly. Since Juno, eclipse contains the m2e maven integration plugin. I suggest you create your first projects using that. It will take care of handling the build process and project setup for you. Use the New->Project...->Maven Project menu and create the project using the wizard. When it is complete, copy all your existing sources into the new one and manipulate the pom file with the pom editor (eclipse will open the pom file with this editor by default.) Important note: If you start using m2e, then don't use the command line eclipse:eclips

Moving to Eclipse RCP from Eclipse plugin development
There are no real differences between RCP and Eclipse IDE applications, except maybe a reduced set of plug-ins to rely on (but they can be brought back). What you might have to take extra care is branding (and theming), and packaging (possible via products). Some RCP tutorials to start with: Eclipse 4 RCP Old, 3.x RCP API Products and deployment In case of RAP, the difference is bigger, as you have to manage the different sessions of different users, and theming is more important. A tutorial for the RAP-based issues (including tips for single sourcing RCP and RAP applications) are available from eclipsesource.com. A final note: if you are starting a brand new project, I'd rather experiment a bit with the 4.x API, as it is simpler to manage between RCP and RAP.

Can't make eclipse open even after change eclipse.ini
According to this Eclipse document: Note the format of the -vm option - it is important to be exact: The -vm option and its value (the path) must be on separate lines. The value must be the full absolute or relative path to the Java executable, not just to the Java home directory. The -vm option must occur before the -vmargs option, since everything after -vmargs is passed directly to the JVM. Note the first requirement. So, try using this somewhere in your .ini file: -vm C:Program FilesJavajdk1.7.0injavaw.exe -vmargs -Dosgi.requiredJavaVersion=1.5 -Xms40m -Xmx512m Note: this is obviously a fragile way to enforce .ini file syntax, and I believe a later version of Eclipse has fixed this potential problem.
