I am unable to build a jar in jenkins slave/master. tried different approach, however unable to resolve this below issue. The same command is helping in locally and am able to create the jar.

export PATH=/opt/apache-maven-3.6.3/bin:$PATH
mvn clean compile -f /home/iburahim/workspace/automation/ -pl testproject -am assembly:single

Finally I found an answer. Issue because of local cli and Jenkins using different java version from slave machine. When i was checking java version in Slave CLI

openjdk version "1.8.0_212" OpenJDK Runtime Environment (IcedTea 3.12.0) (build 1.8.0_212-b4 suse-34.1-x86_64) OpenJDK 64-Bit Server VM (build 25.212-b04, mixed mode)

When i was checking the slave machine java version through jenkins, its returning

19:09:28 + java -version 19:09:29 java version "9.0.4" 19:09:29 Java(TM) SE Runtime Environment (build 9.0.4+11) 19:09:29 Java HotSpot(TM) 64-Bit Server VM (build 9.0.4+11, mixed mode)

Then I found the mismatch and corrected in jenkins slave configuration,

Just added the java home path as /usr/lib64/jvm/jre and ran the job. jar successfully created. I hope this info helpful to someone.
