 * This stage is executed for every pull-request.<br />
 * For non-Docker builds it will execute the respective build (including unit tests, static checks, ...).
 *
 * !!! note "Build Tool not in the list?"
 *
 *     For build tools which are currently not in the list a custom `dockerImage` can be used with a custom `dockerCommand` as per step [buildExecute](../steps/buildExecute.md)
 *
 * For `buildTool: docker` a local Docker build will be executed in case a Docker deamon is available, if not `buildTool: 'kaniko'` will be used instead.
 *
 * ## Advanced Pull-Request Voting
 *
 * It is possible to trigger dedicated tests/checks
 *
 * * pull request comments
 * * pull request labels
 *
 * Following steps are currently supported
 *
 * | step name | comment | pull-request label |
 * | --------- | ------- | ------------------ |
 * | karmaExecuteTests | `/piper karma` | `pr_karma`
 * | whitesourceExecuteScan | `/piper whitesource` | `pr_whitesource`
