How to solve java.lang.NoClassDefFoundError?

Question

I\'ve tried both the example in Oracle\'s Java Tutorials. They both compile fine, but at run-time, both come up with this error:

Exception in thread \"main\"         


        

Answer 1

if you are using gradlew, go to ./gradle/wrapper/gradle-wrapper.properties and change distributionUrl to the correct version of gradle.

If you are using JDK14 try

distributionUrl=https\://services.gradle.org/distributions/gradle-6.3-bin.zip
