sven-lange-last opened a new pull request #2782: Add git pre-commit hook scripts for Scala formatting
URL: https://github.com/apache/incubator-openwhisk/pull/2782
 
 
   Provided scripts can be used to apply project standard Scala formatting automatically
   when committing Scala source files. Developers only need to add the invocation
   of any of the scripts to their git `pre-commit` hook file.
   
   Standard Scala formatting was added with pull request #2650. At the moment,
   https://github.com/apache/incubator-openwhisk/wiki/Contributing:-Git-guidelines#scala
   describes how the `pre-commit` hook can be extended to apply Scala formatting.
   The script provided at this location has some flaws that are addressed by this PR:
   
   * The existing script starts formatting if Scala files are removed.
   * The existing script does not work if no `build.gradle` file can be found
     in the current working directory.
   * The existing script does only consider Scala files in the current
     working directory or below the current working directory.
