I use UFT 14.02 and installed LeanFT with same installer. TestExportTool gives error message below when I execute command:
java -jar "C:\Program Files (x86)\HP\LeanFT\Tools\TestExportTool\test-export-tool.jar" "C:\LeanFT\MyTestNGTests.jar" -classpath:"C:\TestNG\testng.jar"
Invalid signature file digest for Manifest main attributes
I generated artifact with IntelliJ IDEA from TestNG test cases.
