---------------------------------------

             Summary: Distribution sha256 checksum not validated if the zip file was downloaded previously
                 Key: MWRAPPER-93
                 URL: https://issues.apache.org/jira/browse/MWRAPPER-93
             Project: Maven Wrapper
          Issue Type: Bug
          Components: Maven Wrapper Jar
    Affects Versions: 3.2.0
            Reporter: Jorge Solórzano


If I make a first run without *distributionSha256Sum*, the Maven distribution will be downloaded without any checksum, this is the normal behavior.

But if I later add the *distributionSha256Sum* to the maven-wrapper.properties file, having downloaded previously the distribution, the checksum is not verified, I consider this a bug since even if the distribution is already downloaded and unpacked it could contain a compromised download.

The options *alwaysUnpack* and *alwaysDownload* triggers the verification and provides an extra layer of security, but normally the local zip should be verified always if the *distributionSha256Sum* is set.
