This is a tiny extension for the Gradle Wrapper that provides a similar groovyw utility script to go along with gradlew, using the Groovy embedded with the associated version of Gradle to instead execute a plain .groovy script.
Executing either gradlew or groovyw for the first time for a given version will download the Gradle distribution normally. Either script will use the same local files.
This should make using a mix of Gradle and Groovy scripts in a project very convenient as you do not need to manually install Gradle or Groovy, and both will be using the same version of Groovy.
Pick one of the below options:
- Simply grab the files from this repo and add them to an existing project backed by a Gradle Wrapper
gradle/wrapper/groovy-wrapper.jarshould live next to thegradle-wrapper.jargroovywand/orgroovyw.batshould live next to their Gradle variants in the root of a project
- Download a zip file from the Releases tab, extract, place the files accordingly into a local workspace
- Build your own by cloning this repo and running

As of Gradle v6.4 the code innards the Groovy Wrapper relies on finally changed - this was an expected future and just a question of time.
As a consequence a v2 of this wrapper has been prepared and built, and can be used with Gradle 6.4 and onwards, to the next unknown future point of breakage.
However, that may not work with older Gradles, so you may have to use one or the other.
Additionally the 6.4 Gradle no longer ships with commons-io so we can't well put that on the Groovy Wrapper's classpath anymore. Sorry #2 !
Yep, it is Gradles all the way down :-)
The Groovy Wrapper was based on Gradle 3.3 using the wrapper files embedded within this repo (retrieved via regular gradlew wrapper update) along with two edited Java source files from https://github.com/gradle/gradle/tree/master/subprojects/wrapper/src/main/java/org/gradle/wrapper that haven't been changed for some time.
While primary testing was done with 3.3 you can vary the target Gradle version via gradle/wrapper/gradle-wrapper.properties normally and be using that Gradle (and its embedded Groovy) without trouble at least for some versions both back and forward. Older Gradle wrapper jar versions may not function and future changes may also become incompatible with this extension. Any upgrade is likely trivial in effort.
