java.lang.NoSuchMethodError with version 2.0.3

[thees]

I get a java.lang.NoSuchMethodError when I use version 2.0.3. With version 1.5.2 it works.
Using gradle 5.0 or 5.1

My test (in a testset 'functionalTest') uses a function in a package (i.e. not in a class; to create a common test object) like this:

@Test
fun `test insert into db`() {
    assertTimeout(Duration.ofSeconds(7L)) {
        insertObjectIntoDb(aTestObject())
        ...
    }
}

where aTestObject is defined in another kotlin file (also in the same testset):

package com.xyz.company.databasetest

import ...

internal fun aTestObject(version: Long = 1L): TestObject {
    return TestObject(
        id = "id",
        version = version
    )
}

when I run the functionalTests on command line the test fails with a NoSuchMethodError saying that aTestObject method cannot be found.
The error also occurs when I put the argument explicitly in the test (ignoring the default argument in aTestObject method)

    java.lang.NoSuchMethodError: com.xyz.company....TestObjectsKt.aTestObject(J)Lcom/xyz/company/.../TestObject;
        at com.....TestObjectTest$test insert into db$1.execute(TestObjectTest.kt:63)
        at org.junit.jupiter.api.AssertTimeout.lambda$assertTimeout$0(AssertTimeout.java:49)
        at org.junit.jupiter.api.AssertTimeout.assertTimeout(AssertTimeout.java:78)
        at org.junit.jupiter.api.AssertTimeout.assertTimeout(AssertTimeout.java:66)
        at org.junit.jupiter.api.AssertTimeout.assertTimeout(AssertTimeout.java:48)
        at org.junit.jupiter.api.AssertTimeout.assertTimeout(AssertTimeout.java:44)

Strangely the test runs in IntelliJ.

Maybe the error occurs, because the test uses Junit5 "assertTimeout"?

Hi, I've tried to recreate this and couldn't reproduce the error.

If it's working when running the test from IntelliJ, it might mean that the TestObjectKt wrapper class around your function isn't on the test classpath (because IntellIJ test runner manages its own classpath).

Could you please

• check if it's working with the latest version 2.1.0 (there were some fixes to the classpath)
• if it still fails, log the test testClassesDirs and classpath e.g. like this:

tasks.withType<Test> {
    doFirst {
        println ("""
            Test task "$name":
              testClassesDirs: ${testClassesDirs.joinToString()}
              classpath: ${classpath.joinToString()}
        """.trimIndent())
    }
}

The testClassesDirs should have two entries: the directories that end with build/classes/java/functionalTest and build/classes/kotlin/functionalTest.

These two should also be in the classpath.

BTW assertTimeout shouldn't be the issue, it's only on the stacktrace because it's executing the lambda argument.

Hi @tkrullmann ,
I can verify that the bug has been fixed with 2.1.0. I also retested with the old version 2.0.3 where the bug still occured, just to be sure ;-)

Thanks,
Sebastian
