Trouble Building the Plug-in

[Colin Howe]

Have followed all the instructions from the wiki (including getting a fresh install of 3.5 with the correct plug-ins).

I've installed the Scala plug-in from 10th September and I'm having trouble compiling the plug-in. The ant target "prepare" works fine but the compliation of the plug-in fails in Eclipse.

It is failing to import anything from scala.tools.nsc - so I think it's failing to pickup the reference to scala/scala-library properly.

Has anyone seen this before?

Finally got everything working.

For reference:

• Turn off Eclipse auto-building because it'll make everything slow and nasty
• Refresh scala-library and then build it
• Refresh scala-plugin-aspects and then build it
• Refresh scala-plugin and then build it

If Eclipse appears to do nothing when you request a build then it has probably done nothing and thinks everything is built happily. Do a clean (just on the project) - and make sure Eclipse doesn't try to build the workspace automatically.

If your scala-library hasn't been built properly then you will have lots of errors in scala-plugin (particularly about failing to import anything from scala.tools.nsc)

If your scala-plugin-aspects hasn't been built properly then you will have only a few errors (<20) in scala-plugin (particularly about failing to import anything from scala.tools.eclipse.contribution)

Hope that helps someone else :-)

This is good advice for a first build ... thanks for posting.

However, I strongly recommend re-enabling auto-building after that first step.

Cheers,
