----------------------------------------
{{copyProperties( Project antProject, MavenProject mavenProject )}} improved in
[r1798389|http://svn.apache.org/viewvc?rev=1798389&view=rev].
> antrun loops the backing map of java.util.Properties withouth checking type
> safety

> Key: MANTRUN-204
> URL: https://issues.apache.org/jira/browse/MANTRUN-204
> Project: Maven Antrun Plugin
> Issue Type: Bug
> Affects Versions: 1.8
> Environment: seen in maven 3.3.3, maven 3.3.9
> Reporter: Gene Smith
>
> In AntRunMojo's copyProperties method, visible at either of these:
>
> http://svn.apache.org/viewvc/maven/plugins/tags/maven-antrun-plugin-1.8/src/main/java/org/apache/maven/plugin/antrun/AntRunMojo.java?view=markup#l401

> http://grepcode.com/file/repo1.maven.org/maven2/org.apache.maven.plugins/maven-antrun-plugin/1.8/org/apache/maven/plugin/antrun/AntRunMojo.java#AntRunMojo
> This loop does not check the type of objects in the Properties object it is
> looping:
> Properties mavenProps = mavenProject.getProperties();
> for ( Map.Entry<?, ?> entry : mavenProps.entrySet() )
> {
> antProject.setProperty( (String) entry.getKey(), (String)
> entry.getValue() );
> }
> Antrun 1.7 used an iterator and java.util.Properties' getters and setters (so
> the conversion was done for it).
> The Properties object itself allows access to the backing map but strongly
> discourages using it. For type safety, if you loop the entryset you need to
> check types (or check null and call "toString" instead of casting). Maven
> does NOT enforce the type of objects put into that map, so
> some plugins put non String objects in it. (In my use case,
> "org.eclipse.rcptt:rcptt-maven-plugin" stores a boolean in it.)
> ....
> As a work around I antrun 1.7 in this usecase.
