如何修改SAP UI5本地库文件

You meet with issues when you send odata request to backend:

You observe in the local version js file, line 1655, the sUrl population logic is wrong:
the check against length is missing.

In another version of the same file, the expected check logic is there.

You would like to make changes on the local js file.
Step1: find out the jar file name which contains the js file you want to change and also the local path of the jar file in Network tab:

jar file: com.sap.ui5.core_1.24.1.jar

Step2: extract the .jar file, make local changes there:

Step3: re-pack the whole extracted folder via jar command below:

Step4: replace the old jar file with the jar file generated in step3:
C:\myProgram\sapui5-ide-kepler-win32.win32.x86_64\plugins

Relaunch tomcat and the modified source code of .jar file will be loaded.
