BeforeAll throws AbstractMethodError when working with Junit Jupiter M5

[glaed]

• Version of JMockit: 1.33

• Description:

I am using IntelliJ 2017.2.1 which requires me to work with JUnit 5 Milestone 5.
When I try to run any test, I get the following error:

java.lang.AbstractMethodError: mockit.integration.junit5.JMockitExtension.beforeAll(Lorg/junit/jupiter/api/extension/ExtensionContext;)V

This looks like a compatibilty problem of jMockit with Juptiter M5 to me.
Although I have to add that I get a different error when running the tests on the console via Maven:

WARNING: TestEngine with ID 'junit-jupiter' failed to discover tests
java.lang.AbstractMethodError: org.junit.platform.launcher.core.DefaultDiscoveryRequest.getDiscoveryFiltersByType(Ljava/lang/Class;)Ljava/util/List;  
at org.junit.platform.engine.support.filter.ClasspathScanningSupport.buildClassNamePredicate(ClasspathScanningSupport.java:42)

I apologize if this counts as non-reproducible or is not actually related to jmockit.

Here are the relevant parts of my pom.xml:

No problem, as in M4, M5 introduced new breaking API changes, which JMockit needs to adjust to.

Just as an additional information, I encounter the same error with JMockit 1.34.

@matthieusb That's strange. For me, the update fixed the issue and worked well with JUnit 5 Milestone 5 as well as the version 5.0.0.

That's probably not the reason but have you checked which JUnit version is bundled with IntelliJ?

I am using Eclipse. So that's probably a configuration/plugin problem on my side. I have rollbacked my modifications since junit5 is not vital to my current project. But this info will be useful if I try again. Thanks !
