Hi I got below exception with these dependencies.

testCompile 'junit:junit:4.12'

testCompile 'info.cukes:cucumber-junit:1.2.5'

testCompile 'info.cukes:cucumber-java:1.2.5'

testCompile 'org.mockito:mockito-core:2.8.47'

testCompile 'org.assertj:assertj-swing-junit:3.5.0'

testCompile 'com.github.tomakehurst:wiremock:2.6.0'

testCompile 'org.powermock:powermock-module-junit4:1.7.1'

testCompile 'org.powermock:powermock-api-mockito2:1.7.1'

testCompile 'javax.servlet:javax.servlet-api:3.1.0'

I have found some discussion on stackoverflow but it won't help on my case. And it is really strange, everything is good on my local machine and throw exception on our jenkin CI server.

Could you give me some suggestion ?

I did actually. In my case, it was quite silly. I hadn't explicitly specified the junit version and clover was doing sthg (I'm still not sure how and why) where it was pulling a different version. So I specified junit 4.12 and it worked!
