I can't run JUnit 5.9.x tests in Eclipse 2023-09 (4.29.0)

Hi I've start with start.spring.io just like below enter image description here

and I was trying to check if test is okay or not by default. enter image description here enter image description here

but it wasn't even start to it. and I got this error in console instead of test results.

java.lang.NoSuchMethodError: 'java.util.Set org.junit.platform.engine.TestDescriptor.getAncestors()'

I googled. people said that it was seemed that related with jupiter-api version. so I added some dependencies like this. but it didn't work.

// build.gradle
plugins {
    id 'java'
    id 'org.springframework.boot' version '3.1.3'
    id 'io.spring.dependency-management' version '1.1.3'
}

group = 'hello'
version = '0.0.1-SNAPSHOT'

java {
    sourceCompatibility = '17'
}

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-thymeleaf'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    developmentOnly 'org.springframework.boot:spring-boot-devtools'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    
    
    testImplementation('org.junit.jupiter:junit-jupiter-api:5.9.3') /// added version
    testRuntimeOnly('org.junit.jupiter:junit-jupiter-engine:5.9.3') /// added version
}

tasks.named('test') {
    useJUnitPlatform()
}

I also tried in different way. I added Java Build Path on my Eclipse IDE but it didn't work too.
(right click on my project > Properties > Java Build Path
> Modulepath(already tried classpath too.) > Add Library > JUnit

I didn't see same case about JUnit error with 'java.util.Set org.junit.platform.engine.TestDescriptor.getAncestors()'.
so I'm confused now. please help.

Solution

  • This seems an issue of Eclipse Buildship with JUnit less than 5.10.0 and Eclipse 2023-09 (4.29) which I reported here:

    Eclipse Buildship issue #1265: NoSuchMethodError when running a JUnit 5.9.3 test in Eclipse 2023-09 (4.29)

    Workarounds:

    • In build.gradle, add the dependency testImplementation 'org.junit.platform:junit-platform-launcher:1.9.3' or
    • Upgrade to JUnit 5.10.0: testImplementation 'org.junit.jupiter:junit-jupiter:5.10.0'
    • See Daniele Repici's answer for a workaround without changing build.gradle

    Cause:

    It seems Buildship does not choose the corresponding junit-platform-launcher (as m2e seems to do; at least this issue cannot be reproduced with Maven), but uses the junit-platform-launcher version that is shipped with Eclipse. And in Eclipse 4.29 junit-platform-launcher has been upgraded to 1.10.0. But org.junit.platform:junit-platform-launcher:1.10.0 calls org.junit.platform.engine.TestDescriptor.html::getAncestors which has been introduced in org.junit.platform:junit-platform-engine:1.10.0 and which is missing in org.junit.platform:junit-platform-engine:1.9.3 in JUnit 5.9.3.
