Re: [scala-ide-user] error while compiling reflect from scala source

[Simon Schäfer]

The IDE is coupled with scalac, this means you can't compile a 2.11
codebase with an IDE based on 2.10.

I don't know if there is already an update site for 2.11 available but
for the case it is not, you can build it by yourself:

$ git clone https://github.com/scala-ide/scala-ide.git
$ cd scala-ide
$ ./build-all.sh clean install -P scala-2.11.x
-Dscala.version=2.11.0-SNAPSHOT -Dversion.tag=nightly -Dmaven.test.skip=true

After that you have an update site in
scala-ide/org.scala-ide.sdt.update-site/target/site/

I'm going  to try it out. Many thanks.
