| # Java 8 Test Suites |
| |
| These tests require having Java 8 installed and are isolated from the main Spark build. |
| If Java 8 is not your system's default Java version, you will need to point Spark's build |
| to your Java location. 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/ build/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. |
