sbt error: java.lang.NoSuchMethodError: sbt.classpath.ClasspathUtilities$.isArchive$default$2()Z

[Michael Clark]

I'm trying to set up scala in eclipse 4.3 using scala 2.10.0-1, sbt 0.13.0-1, and scala ide 3.0.1-1.  I'm running arch linux, and I've installed scala, sbt, and eclipse from the arch core repos and scala ide from the user repo.

I get the following error when trying to compile a simple HelloWorld app.

java.lang.NoSuchMethodError: sbt.classpath.ClasspathUtilities$.isArchive$default$2()Z

The full stack trace is:

I have almost no experience in eclipse, so I'm having trouble figuring out what the next steps for debugging this issue is.  Should I try installing the 4.0 nightly build?

If you are an adventurer you could go for the nighties.
If you are looking for a functioning scala-ide I would advice to try one of the stable configurations as depicted on http://scala-ide.org/download/current.html (eclipse 4.3 is not listed among them)

good luck!

Thanks for the response.

In the end I just uninstalled all of the packages I installed from arch, and downloaded the eclipse 3.7 / scala ide 3.0.1 bundle straight from the website. Worked like a charm!

Hi Michael,

Good to hear things are working properly now. The error you reported is a binary incompatibility, did you build the IDE yourself when that occur?
