> ParseVersionMojo throws NPE when there is no qualifier
> ------------------------------------------------------
>
> Key: MBUILDHELPER-11
> URL: http://jira.codehaus.org/browse/MBUILDHELPER-11
> Project: Maven 2.x Build Helper Plugin
> Issue Type: Bug
> Affects Versions: 1.3
> Reporter: Horst Studer
> Assignee: Paul Gier
> Priority: Critical
> Fix For: 1.4
>
>
> When the version has no qualifier (like version "1.0.0"), the
> ParseVersionMojo throws a NullPointerException.
> java.lang.NullPointerException
> at java.util.Hashtable.put(Hashtable.java:394)
> at java.util.Properties.setProperty(Properties.java:143)
> at
> org.codehaus.mojo.buildhelper.ParseVersionMojo.execute(ParseVersionMojo.java:108)
> at
> org.apache.maven.plugin.DefaultPluginManager.executeMojo(DefaultPluginManager.java:451)
> The mojo creates an
> org.apache.maven.artifact.versioning.DefaultArtifactVersion from the version
> string.
> The DefaultArtifactVersion returns dafault values of 0 (zero) for all integer
> version parts, but
> getQualifier() returns null if there is no qualifier.
> Thus
> props.setProperty( propertyPrefix + ".qualifier",
> artifactVersion.getQualifier() );
> causes a NullPointerException.
> It would probably be the best solution to set an empty string value if there
> is no qualifier:
> String qualifier = artifactVersion.getQualifier();
> props.setProperty(propertyPrefix + ".qualifier", qualifier != null ?
> qualifier : "");
