I am getting the following error when I start my Spring Boot application.

```

After much searching, I found several instances of this including [java.lang.NoClassDefFoundError: Could not initialize class org.codehaus.groovy.vmplugin.v7.Java7](https://stackoverflow.com/questions/61289461/java-lang-noclassdeffounderror-could-not-initialize-class-org-codehaus-groovy-v), but most are older posts on older versions of gradle and groovy or they are related to android.

Here is my version info:

```
$ gradle -version

------------------------------------------------------------
Gradle 6.6.1
------------------------------------------------------------

Build time:   2020-08-25 16:29:12 UTC
Revision:     f2d1fb54a951d8b11d25748e4711bec8d128d7e3

Kotlin:       1.3.72
Groovy:       2.5.12
Ant:          Apache Ant(TM) version 1.10.8 compiled on May 10 2020
JVM:          14.0.2 (Oracle Corporation 14.0.2+12-46)
OS:           Linux 5.4.0-42-generic amd64

```

I am not doing any groovy apart from my unit tests that are entirely groovy/spock and I'm using gradle for my build engine.

Following directions I found, I went ahead and changed my `gradle-wrapper.properties` file to

```
distributionUrl=https\://services.gradle.org/distributions/gradle-6.6-bin.zip

```

it was 6.5-bin.

This project was running fine on my old computer with Java 8. I moved it to my new workstation and am trying to move to `open JDK 14`, and that is when the new issue started.

Wondering where to go from here.
