invalid target release 1.8

Question

I was try to deploy my application on the OPENSHIFT, but maven can't compile it with error:

invalid target release 1.8

my "build" action_hook:

export JAVA_HOME="${OPENSHIFT_DATA_DIR}jdk1.8.0_05"
export PATH=${OPENSHIFT_DATA_DIR}jdk1.8.0_05/bin:$PATH
cd $OPENSHIFT_REPO_DIR
java -version
mvn package -s .openshift/settings.xml -DskipTests=true

RESULT

java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

then I use this script and see the problem:

export JAVA_HOME=${OPENSHIFT_DATA_DIR}jdk1.8.0_05
export PATH=${OPENSHIFT_DATA_DIR}jdk1.8.0_05/bin:$PATH
java -version

java version "1.8.0_05"

Java(TM) SE Runtime Environment (build 1.8.0_05-b13)

Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

mvn --version | grep 'Java home'

Java home: /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.85/jre

Java Home was changed, but maven ignore new java home. Please help.

Answer 1

You can use WildFly catrtridge. This cartridge has all what you need. Java8, spring boot triggers, and admin panel.

Answer 2

It sounds like your mvn command is setting its own JAVA_HOME. Check the contents of 'mvn' to see what it is doing.

Answer 3

You should try using the java8 marker in your .openshift/markers folder for your project, that should help get maven to use the correct version. That is assuming that you are using one of the standard java cartridges and not a DIY cartridge.
