Compile with javac 1.7 and run with java 1.7 is achieved by those respective commands: $ JAVA_1_6_HOME=/usr/lib/jvm/java-6-sun mvn -X -Pjava-1.6 clean test $ JAVA_1_7_HOME=/usr/lib/jvm/java-7-openjdk-amd64 mvn -X -Pjava-1.7 clean test IIUC: JAVA_x_y_HOME is used to locate the "javac" executable -Pjava-x.y selects the language level JAVA_HOME has no effect This, however, > >> > 3. Compile with javac 1.6 and run with java 1.7 is not so easy. To run the tests with 1.7, one needs $ JAVA_1_6_HOME=/usr/lib/jvm/java-6-sun mvn -Dcommons.surefire.java=/usr/lib/jvm/java-7-openjdk-amd64/bin/java -X -Pjava-1.6 clean test > > [...] Much to my surprise, this $ JAVA_1_7_HOME=/usr/lib/jvm/java-7-openjdk-amd64 mvn -Dcommons.surefire.java=/usr/lib/jvm/java-6-sun/bin/java -X -Pjava-1.7 clean test (i.e. using java 1.6 to run classes compiled with javac 1.7) also works! Is that expected? [I thought I'd get the "incompatible major.minor version" exception.] Best regards, Gilles --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
