2019-10-22 11:41:21 - IllegalArgumentException: Illegal pattern component: XXX

Versions: 2.8.0+


Root Cause: Needs commons-lang3 jar(/opt/infoworks/lib/df) version to be greater than >=3.5


Solution/Workaround:


Navigate to $IW_HOME/lib/df/

Do ls and grep for commons-lang3

If the version is earlier than 3.5(eg : commons-lang3.3.2.jar) thenĀ 

Download the latest version >=3.5.

wget -O /opt/infoworks/lib/df/commons-lang3-3.5.jar https://repo1.maven.org/maven2/org/apache/commons/commons-lang3/3.5/commons-lang3-3.5.jar


Replace the earlier version with the latest downloaded jar.

The rerun of the pipeline build works after these changes.
