Invalid target release 1.8

Question

I tried to deploy my application in OPENHIFT, but maven cannot compile it with an 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) [devlt-chernihiv.rhcloud.com repo]\> mvn package -s .openshift/settings.xml -DskipTests=true [INFO] Scanning for projects...

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)

HotSpot (TM) 64-bit Java Server Virtual Machine (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 has been changed, but maven ignores the new java site. Please, help.

Answer 1

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

Answer 2

You should try using the java8 token in the .openshift / markers folder for your project, which should help make maven use the correct version. It is assumed that you are using one of the standard java cartridges, not a DIY cartridge.

Answer 3

It looks like your mvn team is setting its own JAVA_HOME. Check the contents of "mvn" to see what it does.
