Gradle BootRun fails after generateQueryDSL task finishes executing

HI I am using Gradle 3.1 with Spring-Boot 1.2.4. After performing a git pull in the root directory I then run the command gradle BootRun as usual with success. However, now when I run this command, it seems that the build fails after generateQueryDSL task has finished. I’m not sure that anything has changed. Here is a snippet of the code segment:

13:30:56.988 [DEBUG] [org.gradle.api.internal.tasks.execution.ExecuteAtMostOnceTaskExecuter] Finished executing task ':generateQueryDSL

If you need more info please let me know. Thanks.

OK I believe I fixed it. After some investigation: What happened was that the gradle version I was running was (3.1) was giving me problems. So after looking at the build.gradle (Ruby?) script, I switched to gradle version 2.6. I visited the gradle support community and it was stated - at least back in mid-June - that there were updates made which caused a dependency management spring boot lib file to fail for version 3.1. So that seemed to solve most of the problem however once I got to 83% booted it still failed with Tomcat access error.

It turns out that I had an XAMPP Control monitor running Tomcat (used for PHP I think) so Tomcat was now being used by that app instead of gradle bootRun. When I removed the Tomcat job from that XAMPP application it freed up Tomcat and gave gradle access to it so that I could boot all the dependencies for Awana Club.
