Answer 1

right click project --> properties --> maven --> lifecycle mapping --> check (skip maven compiler plugin) click ok now the build path appears . nw do the necessary changes

Answer 2

Problem was solved simply by deleting the project from my workspace, deleting all .project, .classpath files and .settings folders, and re-importing. I don't know why it didn't work the first time. Thanks for the help, everyone.

Answer 3

Make sure if you have M2 plugin in Eclipse, you have Maven 2.7 above installed in your system.

After that run mvn eclipse:clean then mvn eclipse:eclipse.

.classpath and .project will be created in your project folders. Everything should be fine.

Answer 4

The Project nature is decided by the .project file in Eclipse, which also dictates to Eclipse about the Parent Source Code, and Test Folders.

Update/Modify the .project file as follows, using which We retain the Maven Compatibility and Java Nature of the Project.

.project.xml under the Eclipse Project folder

<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
        <name>java-cgdk-en</name>
        <comment></comment>
        <projects>
        </projects>
        <buildSpec>
                <buildCommand>
                        <name>org.eclipse.jdt.core.javabuilder</name>
                        <arguments>
                        </arguments>
                </buildCommand>
        </buildSpec>  
        <natures>
                <nature>org.eclipse.jdt.core.javanature</nature>
        </natures>
</projectDescription>

Answer 5

Install m2e and subclipse from the Eclipse Marketplace depending on what version of Eclipse you have. Then:

1. Open Eclipse go to Window > Open Perspective > Other... > SVN Repository Exploring.
2. Add your svn url to SVN repository/code base.
3. Select a project. Right Click and select Checkout.
4. Assuming your project has a pom.xml, switch back to your Java perspective, select the project that was just imported, right click and select Configure > Convert to Maven Project.

It should now be recognized as both a Maven and a Java project (Maven and Java natures will have been added to the Eclipse .project file)

Answer 6

I'm using Version: Indigo Service Release 2 Build id: 20120216-1857

I also found that after I installed the Maven plugin that 'Project Explorer' - Right click on 'my project' did not list option "Maven" or "configure".

On reading the above, I tried doing the same on "Package Explorer" and to my surprise it worked. And now 'Project Explorer' works too!
