In a new workspace
- create a project
- in the package explorer, browse to a class inside scala-reflect.jar inside the 'Scala library' classpath container.
- open the class. The javap like editor opens, there are no sources associated with this jar.
In ScalaClasspathContainer, an attempt is made to link the jar to a source jar at target/src/scala-reflect-src.jar, but this file doesn't exists. It is not copied over during the build.
- install the 'Scala IDE for Eclipse Source' feature from the update site
- import a plugin project which depends on scala-reflect, like org.scala-ide.sdt.org.
This will create the correct association between the jar and the source jar, and it will be available in simple Scala projects.
