Answer 1

I faced the same issue with Eclipse few days ago.

So I tried to find the library that proposed the same package ( javax.xml.namespace ) already available in the javax.xml Java built-in module, provoking package duplication.

In my case it was a lybrary under the name stax-api . I just removed it from the build, like this:

dependencies {
...
  configurations {
       compile.exclude group: 'stax', module: 'stax-api'
  }
...
}
