   > Did you also have a problem with JaCoCO:0.7.9 on JDK10?
   
   According to https://github.com/jacoco/jacoco/releases 0.8.1 introduced JDK 
10 support. Thus, 0.7.9 had to fail.
   
   > Do we need to have scope=compile on the dependency 
<artifactId>junit-platform-launcher</artifactId> in our provider POM? What will 
happen if it would be scope provided?
   
   99% yes, the provider needs it at compile time. That's what JUnit Platform 
is all about. It's the API for tools (build tools, IDEs, ...) to get "JUnit 5" 
_(technically, there's no JUnit 5)_ running. See this import statements in 
`org.apache.maven.surefire.junitplatform.JUnitPlatformProvider`:
   
   ```java
   import org.junit.platform.launcher.Launcher;
   import org.junit.platform.launcher.LauncherDiscoveryRequest;
   import org.junit.platform.launcher.TagFilter;
   import org.junit.platform.launcher.core.LauncherDiscoveryRequestBuilder;
   import org.junit.platform.launcher.core.LauncherFactory;
   ```
   
   And recall the "JUnit 5" architecture layout:

   Just move the **junit-platform-surefire-provider** from the bottom-left out 
off the red **PLATFORM** box into the **IDEs/Build Tool** bubble at the bottom. 
Here be dragons, Gradle, Surefire, IDEA, Eclipse, etc...
   
   1% no, perhaps there's some Maven-trick to achieve the same with `provided` 
scope?
   
   > How did you skip tests on surefire-junit-platform with JDK 1.7?
   
   Mh, if it is because of `<jvm>${java.home}/bin/java</jvm>` then @britter did 
it.
   At test runtime, the assumption declared in `JUnitPlatformIT` ensures that a 
JDK 1.8+ is at work:
   
   ```java
   @Before
   public void setUp()
   {
       assumeThat( "java.specification.version: ",
                       getProperty( "java.specification.version" ),
                       is( greaterThanOrEqualTo( "1.8" ) ) );
   }
   ```
