Successful build in Maven still showing errors in Eclipse

Question

I\'m having something quite peculiar here, my build is successful in maven when I type \"mvn clean install\" however once imported into Eclipse it\'s showing errors.

Answer 1

You've a library (quartz-1.5.2.jar) that's reference to your m2 local repository which doesn't exist if you just remove the quartz from your build path and update your dependencies internally(in eclipse) that would solve the problem

Answer 2

You should try mvn eclipse:eclipse

And then make sure the M2_REPO variable is point to your local repository.

Answer 3

In my case, eclipse starts to show all errors after I changed some versions of dependencies in pom.xml, however the command line mvn clean install build successfully

1. I deleted folders of the dependencies I changed manually from the .m2 repositories (in my case everything under org.apache.beam), because I also has corrupted dependency issues.
2. mvn clean build the project, this downloaded the dependencies again
3. right click project: maven -> update project
4. delete the project from eclipse (but not from disk) and reimport (this actually left me with 1 error still, then i delete and reimported again)

Answer 4

In my case there were also problems with Java build path like the following: "Build path specifies execution environment J2SE-1.5. There are no JREs installed in the workspace that are strictly compatible with this environment." Fixing this resolved compilation errors.

Answer 5

If you don't see any error in Eclipse project but it keeps showing the red icon on your project name. Try mvn eclipse:eclipse.

Then select all projects in Eclipse, Right click > Maven > Update projects

Hope it helps.

Answer 6

That often happens when the m2eclipse hasn't updated the build path to correspond to what a modified POM file says. There's an entry in the Maven context menu to update the Configuration.
