Thanks, that solved the problem. maven was pointing to a different java even after setting the JAVA_HOME. Have reinstalled maven Now build is working.

So just final verification, what "mvn -v" reports?
This is what I got on FC29, where everything works fine for me:

$ mvn -v
Apache Maven 3.5.4 (Red Hat 3.5.4-4)
Maven home: /usr/share/maven
Java version: 11.0.4, vendor: Oracle Corporation, runtime: /usr/lib/jvm/java-11-openjdk-11.0.4.11-0.fc29.x86_64
Default locale: en_GB, platform encoding: UTF-8
OS name: "linux", version: "5.2.18-100.fc29.x86_64", arch: "amd64", family: "unix"

$ echo $JAVA_HOME
/usr/lib/jvm/java-11

Hi,
java -version does report jdk 11. Previously I did set it up with alternatives.Any idea?

java -version
openjdk version "11.0.5" 2019-10-15
OpenJDK Runtime Environment 18.9 (build 11.0.5+10)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.5+10, mixed mode, sharing)

Try to execute "java -version". If it doesn't report JDK 11, then you need to set it using alternatives:

Did you set JAVA_HOME to point to java 11 jdk?
