SBT java.io.IOException: Not in GZIP format

Question

A Windows 7 Pro machine was shut down improperly. When the machine came back up, running 'sbt test' resulted in this error:

[error] {file:/C:/Jenkins/jobs/job1/workspace/}default-2990ce/copy-resources: Error wrapping InputStream in GZIPInputStream: java.io.IOException: Not in GZIP format

How can this be fixed?

Answer 1

I just had this issue after a computer crash and sbt clean didn't help. Make sure you really find and remove all target directories:

 rm -rf `find . -name target`
