Re: [m2e-users] Validation error with maven-bundle-plugin "Unable to load the mojo 'manifest'"
|
Hi AURÉLIEN,
the Maven-Bundle-Plugin since version 3.2.0 supports M2E natively (https://issues.apache.org/jira/browse/FELIX-4009). Unfortunately that conflicts with m2e-tycho (https://github.com/tesla/m2eclipse-tycho). Since the latter also does no longer seem to be maintained (when it comes to maven-bundle-plugin) you can prevent the error by just removing that extension from Eclipse. Actually the exception comes from that extension.
