Java Snap on Rasp-pi

snapcraft

I am building a java application on rasp-pi. The same application has been built as a snap before for amd64.
Here is the java part in my snapcraft.yaml:

main:
   build-packages: 
       - openjdk-8-jre-headless
   stage-packages: 
       - openjdk-8-jdk
   plugin: ant
   source: .
   override-build: |
       export JAVA_TO_USE="/usr/lib/jvm/java-8-openjdk-amd64"
       export JAVA_HOME="$SNAPCRAFT_PART_INSTALL$JAVA_TO_USE"
       ant
       mkdir $SNAPCRAFT_PART_INSTALL/jar
       mv $SNAPCRAFT_PART_BUILD/target/*.jar $SNAPCRAFT_PART_INSTALL/jar

The build fails with this error:

Could not find a required package in ‘build-packages’: openjdk-9-jdk-headless.

How can I instruct snapcraft not to look for Java 9. Or why is it failing to find this?

The ant plugin may require java 9 by default, but you can change it with ant-openjdk-version, see snapcraft help ant for more details about the ant plugin
