[dependabot-preview[bot]]

Bumps gmavenplus-plugin from 1.8.1 to 1.9.0.

Release notes

Sourced from gmavenplus-plugin's releases.

1.9.0

Bugs

None

Enhancements

• Support for Java 14 (#152).
• Support for Java 15 (#153).
• Add skipBytecodeCheck property and parameter, so if a Java version comes out the plugin doesn't recognize, you can use it without having to wait for an update.
• Use groovy.ant.AntBuilder instead of groovy.util.AntBuilder (if available).

Potentially breaking changes

• maven.groovydoc.skip property was renamed to skipGroovydoc so it matches the pattern of the other properties and won't seem to imply it's a property for a standard Maven plugin.
• Using groovy.ant.AntBuilder instead of groovy.util.AntBuilder (when available on classpath).
• Bundling Ant 1.10.7 instead of 1.10.5.
• Bundling Ivy 2.5.0 instead of 2.4.0.

Notes

• Now officially requires Java 7 instead of 6. This is not a breaking change, however, since this was actually already required because of plexus-classworlds. This just wasn't discovered until an enforcer rule was added to check bytecode versions of dependencies.
