I'm using terracotta 3.7.0 and I recently deleted my entire .m2 dir, so I have to re-install it. But the build is stuck with error
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5.1:compile (default-compile) on project my-cache: Compilation failure

[ERROR] -> [Help 1]
Does anyone know what might cause this?
UPDATED: when I delete the entire .m2 again, I get this error. NOT terracotta anymore, but maven-jar-plugin. I have a feeling something must've gone wrong with maven.

Does this ring any bell for anyone?
Lots of things could possibly cause this, including:
There are (obvious) things you could try to diagnose these.
It is also possible that some a maven config or repository issue is preventing maven from downloading the file. But there should be something in the output to say that.
You could also try running the
mvncommand with verbose logging enabled; usemvn --helpto list the command line options.That looks like you have managed to fetch a corrupt checksum. Or more precisely, that the remote server gave you an error page when you attempted to fetch the checksum.
