(patch) no useful error message when M2_HOME is misconfigured during bootstrap
------------------------------------------------------------------------------
Key: MNG-2560
URL: http://jira.codehaus.org/browse/MNG-2560
Project: Maven 2
Issue Type: Bug
Components: Bootstrap & Build
Affects Versions: 2.1
Reporter: Dan Fabulich
Attachments: patch.txt
Run the bootstrap build, but configure M2_HOME to be some random directory
"foo". The tests will fail as maven will be installed into
foo/../maven-2.1-SNAPSHOT, but then configured to actually use "foo" as the
execution directory.
The attached patch modifies the BootstrapInstaller to accept a "destDir"
instead of a "prefix", and then double-checks that the destDir is a validly
named destination before actually running the build. This allows the build to
fail clearly and fast when this common configuration error is made. The README
is also updated to highlight more clearly that you *must* M2_HOME correctly in
order for the build to work.
