convert maven project to eclipse
I'm working on a project that has lots of different Maven projects. I've been doing a bunch of JUnit testing on these projects, and usually this goes well. I open up Eclipse, right click in package explorer->Import... Existing Maven Projects and I'm able to import the project fine. I can build, drill down to src/test/java... Right click on the file and do a Run As JUnit test. Every now and then though, I can't get this to work. If I right click to do a Run As, all I get is AspectJ/Java application. There's no JUnit tests.
I noticed that the icon next to the project folder only has an M and a folder icon, whereas with projects that do work, there's a folder, M, AND a AJ. I've also noticed that it doesn't seem to sort the files into their packages like normal Java projects. It seems like it's not treating the project as an AspectJ project. How do I get Eclipse to recognize this Maven project as a Java project?
Several of the existing answers should work, but those suggesting to add a Java facet will only work if your project already is of (or you want to convert it to) a faceted nature, and the one suggesting you change your
pom.xml will only work if you then re-import your project as a maven project.
If you'd like to "fix" your existing project, i.e. add a Java nature without converting it to faceted form and without deleting and re-importing, just edit your
.project file (externally, or with the Navigator view in eclipse, as it won't show up in your package explorer) and add the java builder and java nature to the existing maven builder/nature:
<?xml version="1.0" encoding="UTF-8"?> <projectDescription> <name>yourprojectname</name> <comment></comment> <projects> </projects> <buildSpec> <!-- add this build command --> <buildCommand> <name>org.eclipse.jdt.core.javabuilder</name> <arguments> </arguments> </buildCommand> <!-- this would've already been there --> <buildCommand> <name>org.eclipse.m2e.core.maven2Builder</name> <arguments> </arguments> </buildCommand> </buildSpec> <natures> <!-- add this nature --> <nature>org.eclipse.jdt.core.javanature</nature> <!-- this would've already been there --> <nature>org.eclipse.m2e.core.maven2Nature</nature> </natures> </projectDescription>
Note the different capitalisation (javabuilder but maven2Builder, javanature but maven2Nature).
As soon as you save, it should re-build automatically. You may have to manually add any source folders (

- can you figure out then what's the difference between those two projects, the one where you do get RunAsJunit and the one where you don't get it? pom.xml probably has the answer.
- I found just deleting the .project files and re-importing the poms also fixed this - I cannot figure out how it gets into this bad state though.
- But now all my imports and I have over 4000 build errors.
- @demongolem: Sorry, but how are your build errors related to my answer? If you're having build problems after adding a Java nature to your project, you may want to ask a separate question.
- @demongolem: Of course my suggestion won't fix any build issues "your imports and you" may have. (That's a completely separate problem, which is why I suggested a separate question.) What it will do is add a Java nature to a project that was previously not recognised as a Java project. Obviously once Eclipse tries to rebuild it, you may have to do other things to get it to build without errors, and obviously, if your project didn't build at all before and it does after you've added a Java nature, you'll have to resolve any build errors. My answer never pretended to resolve those for you...
- @nessa.gp I suggest you file a bug report with Eclipse, because this answer is essentially telling you how to work around an Eclipse bug
- Thank you, Perfect !!
- I have the same problem, there is no Facets in properties
- It may also be necessary to perform a
mvn eclipse:cleanprior to the
mvn eclipse:eclipsecommand. Finally
alt+F5and the project was back on track in my eclipse workspace
- This answer worked well me. Also I think its the cleanest approach. thanks !
- This is such a better answer than the top one. By adding a java facet editting the .project or with the user interface made me go through each module of the project setting up the build path. With this instead it is automatic.
- I think this is a solution for a lot of people and other issues. Will redirect them to this answer. Thanks a lot
