> [INFO] Failed to configure plugin parameters for:
> org.apache.maven.plugins:maven-resources-plugin:2.2
> Cause: Cannot assign value '[local] -> file://repo' to field:
> org.apache.maven.plugin.resources.ResourcesMojo.encoding;
> type: org.apache.maven.artifact.repository.DefaultArtifactRepository
> {noformat}
> Although this exploit is rather artificial, it demonstrates the problem. We
> have never properly reserved certain parameter expressions for usage by the
> core to inject magic values. Last but not least, we occasionally extend the
> list of supported expressions in newer Maven versions. That means we're in a
> bad position to demand plugin authors to not use these expressions. Hence we
> need to gracefully handle plugins that use this magic expressions for
> ordinary system properties.
> The real-life example of this issue is MNG-3683, where the Help Plugin uses
> {{${plugin}}} for a String-typed parameter but a new Maven version started to
> use this expression to inject the plugin descriptor.
