maven-scala-plugin:2.14 missing class with Hudson

[rossputin]

Hi Guys.

Since maven-scala-plugin:2.14 was released our Hudson breaks on its
mvn builds with :

[INFO] Internal error in the plugin manager executing goal 'org.scala-
tools:maven-scala-plugin:2.14:compile':
Unable to load the mojo 'org.scala-tools:maven-scala-plugin:
2.14:compile' in the plugin 'org.scala-tools:maven-scala-plugin'.
A required class is missing: org/apache/maven/shared/dependency/tree/
filter/DependencyNodeFilter

org.apache.maven.shared.dependency.tree.filter.DependencyNodeFilter

any ideas ?

Cheers,

Hi,

What is the maven version used by Hudson ?

I'll search which part of the plugin need this class.

Hi.

In case it helps, I have a 2.14-SNAPSHOT, and 2.14 jar which when
dropped in

../.m2/repository/org/scala-tools/maven-scala-plugin

fixes the problem, I can not figure out how to attach here though.

I have not had time to invest in researching the contents of the two
jars, but presumably it is because the snapshot has the required
class ?

If you need them I can email them to you.

Cheers,

-- Ross
