Using following versions
OS : Ubuntu 18.04.1
Jenkins : 2.263.4
Java : 1.8.0_181 ( Master & Slave )
Set JAVA_ARGS="-Xmx2048m" in /etc/default/jenkins( Master )
How can I fix this ?
Java has a 64K size limit on bytecode. It is not an issue with Jenkins. To solve this, you should break apart your pipeline into methods. There is a great example here.
