Unable to run spring boot batch job from PCF CLI with ClassNotFoundException

Question

I am trying to run a spring boot batch job from PCF CLI using the command:

cf run-task TEST_APP “.Java-buildpack/oracle_jre/bin/java org/springframework/boot/loader/JarLauncher -D jobName=job1”

But the task is failing with the following error in logs:

ERR Error: Could not find or load main class org.springframework.boot.loader.JarLauncher
ERR Caused by: Java.lang.ClassNotFoundException: org.springframework.boot.loader.JarLauncher

Please advise.

Answer 1

It works fine with open_jdk_jre...

cf run-task TEST_APP ".java-buildpack/open_jdk_jre/bin/java org/springframework/boot/loader/JarLauncher -D jobName=job"

Seems you have oracle_jre so give it a try:

cf run-task TEST_APP ".java-buildpack/oracle_jre/bin/java org.springframework.boot.loader.JarLauncher -D jobName=job1"
