there 3 error messages displayed:

on line1:

multiple annotations found @ line: - null (org.apache.maven.plugins:maven-resources-plugin:2.5:resources:default-resources:process-resources) - null (org.apache.maven.plugins:maven-resources-plugin:2.5:testresources:default-testresources:process-test- resources)

on line70:

multiple annotations found @ line: - project build error: 'dependencies.dependency.groupid' null::jar missing. - project build error: 'dependencies.dependency.version' null::jar missing.

on line 71:

project build error: 'dependencies.dependency.artifactid' null::jar missing.

it seems 1 on line 70 empty tags root cause (excerpt below) i'm not sure.

<dependency> <artifactid></artifactid> </dependency>

even if delete empty tags xml , refresh maven , project error remains. on dependencies tab see jar '?' next can't delete , in dependency hierachy tab see ' : [compile]' jar can delete or exclude it.

how can remove ghost/null jar?
