exists-maven-plugin v0.1.0 incompatibility with maven 3.3.9 and older

[oliverlockwood]

If you try to use v0.1.0 of this plugin on an older version of Maven, you will experience symptoms similar to those described in jeremylong/DependencyCheck#1054.

v0.0.6 continues to work fine.

I had upgraded this after reviewing the output of mvn versions:display-plugin-updates; while some new plugin versions specified that they would require a minimum of e.g. 3.5.4, this one did not:

[INFO] The following plugin updates are available:
[INFO]   org.honton.chas:exists-maven-plugin ................ 0.0.6 -> 0.1.0
[INFO]
[INFO] Project inherits minimum Maven version as: 3.3.9
[INFO] Plugins require minimum Maven version of: 3.3.9
[INFO]
[INFO] Require Maven 3.5.4 to use the following plugin updates:
[INFO]   org.codehaus.mojo:license-maven-plugin .............. 1.20 -> 2.0.0

Perhaps you could ensure that the published plugin compatibility is accurate, to avoid other people encountering the same issue?

Thanks!

Thanks for the report.
I've updated the readme to indicate minimum required versions.
Next release will enforce the minimum required versions for java and maven.

Sounds reasonable to me. Since changing and republishing artifacts is generally a Bad Thing, I can't ask for more so I think we can consider this issue closed.

Thanks!
