Hi Team,


we are planning to export the workitems from CLM to an excel file. We have downloaded WCL and java plain libraries from Jazz and IBM portal. We configured the wcl.bat file and when we ran the wcl file, we are getting no main manifest attribute error. Please help me to resolve the issue. Please find the error snippet

C:\Users\nu804\Downloads\WCL-V6.1-20240216 (1)\WCL>"C:\Program Files\Java\jdk1.8.0_51\bin\java" -Djava.security.policy=rmi_no.policy -Djava.ext.dirs="C:\Program Files\Java\jdk1.8.0_51\bin\lib\ext;./lib;C:\Users\nu804\Downloads\RTC-Client-plainJavaLib-6.0.6.1" -cp "./lib;C:\Users\nu804\Downloads\RTC-Client-plainJavaLib-6.0.6.1" -jar wcl.jar
Picked up _JAVA_OPTIONS: -Djava.net.preferIPv4Stack=true
no main manifest attribute, in wcl.jar

Consider using https://github.com/jazz-community/work-item-command-line/releases/tag/WCL-V5.3.1 and follow the setup instructions of that version. Newer WCL versions support only EWM 7.x. The latest version of WCL changed how the tool is packaged and launched.

I am not available for more help this week.
