I need to launch a JVM from a Python script. For this I'm trying to use subprocess.run. One of the arguments to the JVM is the classpath. In Windows the separator in a Java classpath is the semicolon ;. I need to add several JARs to the classpath. This works perfectly fine when I manually launch the JVM from the command line. But when I try to launch it with subprocess.run it seems like the part of the classpath which is after the semicolon is ignored. I suspect this has something to do with the fact that the semicolon is the Windows command separator. Anyone knows how to get around it? Failing code def run_groovy_script(groovy_script: str, *args): # This function calls sys.exit in case of error. The idea is to run several commands in sequence and immediately abort with error message if one fails. # Construct the command to run the Groovy script with arguments command = ["groovy.bat", "-cp", "tools/slf4j-simple-2.0.13.jar;tools", groovy_script] + list(args) try: result = subprocess.run(command, check=True) except subprocess.CalledProcessError as e: print(f"{groovy_script} failed with return code {e.returncode}") sys.exit(1) except Exception as e: print(f"An error occurred executing {groovy_script}: {str(e)}") sys.exit(1) Successful cmd invocation groovy.bat -cp "tools/slf4j-simple-2.0.13.jar;tools" tools/script.groovy build hej Continue reading...
