java.util.zip.ZipException: duplicate entry with .m2 and .ivy2

[tekener]

We are running into a problem in case that a lib exists in the .m2 and .ivy2 directory. The workaround is to delete the lib in one of the directories.

The exception:

The debug trace of the war plugin:

Do you know why commons-lang3 is present twice in classpath ? (Ivy and M2 dependencies)

[tekener]

I don't have a glue. The build servers are also running maven builds. Thats why we have the jar in both directories. But i don't know why sbt puts the jar twice into the classpath.

Can you precise:

• SBT version
• Play2war version

Thanks

[tekener]

SBT: 0.13.9
Play2war: 1.3-beta3

Thanks

There is a similar bug in sbt: sbt/sbt-native-packager#657
