java.lang.NoClassDefFoundError at Class.java:-2

Question

Having following code: https://github.com/arturmkr/myReportProblem

Using Java 11.

When I try to execute it I am having issue:

./gradlew clean ui:test 

> Task :ui:test FAILED

com.db.demo.ui.DummyCheck > initializationError FAILED
    java.lang.NoClassDefFoundError at Class.java:-2
        Caused by: java.lang.ClassNotFoundException at BuiltinClassLoader.java:581

1 test completed, 1 failed

Who could help?

There's no DummyCheck class at the link you provided. There's only a UiApplication class. Are you sure you provide the correct link? — Onur Baştürk

@OnurBaştürk, Yes, it's in the test directory. path: /ui/src/test/java/com/db/demo/ui/DummyCheck.java — Artur

Ok you're right. Check out mkyong.com/gradle/gradle-create-a-jar-file-with-dependencies and discuss.gradle.org/t/how-to-include-dependencies-in-jar/19571 while i'm trying your code — Onur Baştürk

Ok now it works (but your tests fail):

Add to your non-Spring boot project's build.gradle (I mean your repository project's build.gradle)


    bootJar 
    {
        enabled = false
    }

    jar 
    {
        enabled = true
    }

./gradlew clean build

It doesn't help.

Well I downloaded your code and opened it in Intellij IDEA. Then added this part to the build.gradle and it worked. Check out your project in a clean directory and try again. May be it helps. Is it the same error again? Any other logs?

I just removed from build.gradle.kts:

jar { enabled = false }

And it helped
