Upgrading the project’s JUnit version to 5.8.0 led to the following failure:
% ./gradlew :yabumi:test > Task :yabumi:test FAILED FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':yabumi:test'. > There were failing tests. See the report at: file:///Users/yusuke/yabumi/yabumi/build/reports/tests/test/index.html * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights. * Get more help at https://help.gradle.org BUILD FAILED in 5s 28 actionable tasks: 2 executed, 26 up-to-date
Interestingly no failed tests were reported.
The root cause of the issue is “Caused by: java.lang.NoSuchMethodError: ‘java.util.Optional org.junit.platform.commons.util.AnnotationUtils.findAnnotation(java.lang.Class, java.lang.Class, boolean)'”.
NoSuchMethodError indicates that there are some dependency conflicts, and it turn out
org.springframework.boot:spring-boot-starter-test:2.5.5 is depending on org.junit.jupiter:junit-jupiter:5.7.2.
Problem solved by excluding org.junit.jupiter:junit-jupiter from org.springframework.boot:spring-boot-starter-test dependency as follows:
testImplementation('org.springframework.boot:spring-boot-starter-test:2.5.5') {
exclude group: 'org.junit.jupiter', module: 'junit-jupiter'
}
testImplementation 'org.junit.jupiter:junit-jupiter:5.8.1'Here’s the actual diff from my project.
Here’s the full stacktrace reported in the html:
