Verify JAVA_HOME for Improved Error Messages
--------------------------------------------
Key: BUILDR-289
URL: https://issues.apache.org/jira/browse/BUILDR-289
Project: Buildr
Issue Type: Bug
Components: Core features
Affects Versions: 1.3.4
Reporter: Daniel Spiewak
Assignee: Daniel Spiewak
Fix For: 1.3.5
Buildr uses the JAVA_HOME environment variable for a number of core tasks.
However, if that variable does not point to a valid JDK, the result will be a
failure at some point with a generally confusing error message (usually
something on the order of " /bin/java does not exist"). We should actually
check to make sure that JAVA_HOME is valid before attempting to use it for the
first time. This check could be as simple as looking for rt.jar and a few of
the executables.
