Dan Haywood commented on MRELEASE-680:
--------------------------------------
Woohoo. Looks like it does work on 2.1. I guess you can close.
> Fails on cygwin with multiline module with nullpointer exception.

> Key: MRELEASE-680
> URL: http://jira.codehaus.org/browse/MRELEASE-680
> Project: Maven 2.x Release Plugin
> Issue Type: Bug
> Components: prepare
> Affects Versions: 2.0
> Environment: cygwin on Windows 7 (and probably earlier Windows
> versions too).
> Reporter: Dan Haywood
>
> Was failing with a nullpointer exception. I downloaded the source and added
> some println statements to ReleaseUtil.java (in mvn-release-manager), so it's
> easy enough to see:
> First I added:
> public static String getCommonBasedir( List reactorProjects, char
> separator )
> {
> System.out.println("ReleaseUtil#getCommonBaseDir()");
> ...
> and in the main loop of this same method I added:
> // added:start
> System.out.println(" - dir : " + dir );
> // added:end
> if ( basedir == null )
> {
> basedir = dir;
> }
> else
> ...
> Also, I added:
> public static int getBaseWorkingDirectoryParentCount( String basedir,
> String workingDirectory )
> {
> System.out.println("getBaseWorkingDirectoryParentCount()");
> System.out.println(" ** basedir : " + basedir );
> System.out.println(" ** workingDirectory : " + workingDirectory );
> ...
> When I ran:
> mvn release:clean release:prepare -P apache-release -D dryRun=true
> then I got:
