             Summary: Avoid overwrite of the destination file if the produced contents is the same
                 Key: MRRESOURCES-91
                 URL: https://jira.codehaus.org/browse/MRRESOURCES-91
             Project: Maven Remote Resources Plugin
          Issue Type: Bug
    Affects Versions: 1.5
            Reporter: Vladimir Sitnikov


maven-remote-resource-plugin is used in Apache pom to add DEPENDENCIES, and the resulting file is overwritten on each build.

It leads to jar being rebuild, etc leading to longer compilation times.

I suggest to compare the produced contents with the existing file.
If both are equal, skip the file being overwritten.

The net win is subsequent build times are improved.

Here's pull request that fixes the problem: https://github.com/apache/maven-plugins/pull/40
