[jira] [Created] (MSHARED-884) Only overwrite filtered resources when contents differ

Robert James Oxspring created MSHARED-884:
---------------------------------------------

             Summary: Only overwrite filtered resources when contents differ
                 Key: MSHARED-884
                 URL: https://issues.apache.org/jira/browse/MSHARED-884
             Project: Maven Shared Components
          Issue Type: Improvement
          Components: maven-filtering
            Reporter: Robert James Oxspring


When filtering files with the {{MavenFileFilter.copyFile}} method, the destination file should only be overwritten if the contents have changed. Currently we unconditionally overwrite the contents in this situation, potentially leading to unnecessary downstream work. When the {{overwrite}} parameter is {{true}} then overwriting should overwrite as it does now.

Given a {{copyFile}} call
When an identical filterFile operation is performed
Then the destination file should remain unmodified

Given a {{copyFile}} call with {{overwrite}} set {{true}}
When an identical filterFile operation is performed
Then the destination file should be overwritten
