macroparadise/4.x nightly Crash IDE Scala Compiler: java.lang.NoSuchMethodError: scala.tools.nsc.Settings.lint()
Attached is a full example project.
TLDR; macroparadise as the nightly Scala IDE are generating a Scala IDE Compiler Crash.

I just checked, even if I bump to the paradise SNAPSHOT I still get the compiler crash.
libraryDependencies += compilerPlugin("org.scalamacros" % "paradise" % "2.1.0-SNAPSHOT" cross CrossVersion.full))
libraryDependencies += compilerPlugin("org.scalamacros" % "paradise" % "2.1.0-SNAPSHOT" cross CrossVersion.full))

Looks like this is fixed if you use paradise "2.1.0-SNAPSHOT" with 2.11.2

By ericpeters
ALSO looks like simply using the 2.11.2 scala versino for the project and using the old 2.0.1 paradise also works...so guess the solution was to bump my projects to the new 2.11.2 release
Check compiler plugins for version conflicts and cleanup
PC options in case of incompatibilities.
Compiler plugins (like macro-paradise) are cross-compiled with
the full Scala version, and they are not binary compatible across
minor versions. We acknowledge that and check it properly in the
classpath validator.
Compiler plugins can’t be instantiated in the PC unless the
project Scala version (Installation) is exactly the same as
the platform (the one Eclipse is running). This commit fixes PC
crashes due to such incompatibilities.
