The set-up depends a bit on the build system: + +* Sbt users can either set JAVA_HOME to the location of a Java 8 JDK or explicitly pass + `-java-home` to the sbt launch script. If a Java 8 JDK is detected sbt will automatically + include the Java 8 test project. + + `$ JAVA_HOME=/opt/jdk1.8.0/ sbt/sbt clean "test-only org.apache.spark.Java8APISuite"` + +* For Maven users, + + Maven users can also refer to their Java 8 directory using JAVA_HOME. However, Maven will not + automatically detect the presence of a Java 8 JDK, so a special build profile `-Pjava8-tests` + must be used. + + `$ JAVA_HOME=/opt/jdk1.8.0/ mvn clean install -DskipTests` + `$ JAVA_HOME=/opt/jdk1.8.0/ mvn test -Pjava8-tests -DwildcardSuites=org.apache.spark.Java8APISuite` + + Note that the above command can only be run from project root directory since this module + depends on core and the test-jars of core and streaming. This means an install step is + required to make the test dependencies visible to the Java 8 sub-project. |
