jar-exec

Executes a specified command passed in via an argument. Pipes stdin and stdout. Also puts logs to logs/latest.log to work with Crafty Controller.

Building

Make sure you have Java and Maven installed.

mvn clean
mvn package

Running

Make sure you have Java installed. Copy jar-exec-jar-with-dependencies.jar or jar-exec.jar and the dependency-jars directory to the location you want to use jar-exec in.

You can put --disable-dt-log before the command to get run (Example: java -jar target/jar-exec-jar-with-dependencies.jar --disable-dt-log "python tester.py") to disable date and time log information if the application you are running does that, see Example Logs section for more.

Example usage:

If you copied the jar with the dependencies:

java -jar jar-exec-jar-with-dependencies.jar "python tester.py"

If you copied jar-exec.jar and the dependency-jars directory:

java -jar jar-exec.jar "python tester.py"

You can download tester.py from https://www.thatonelukas.tk/files/jar-exec/tester.py or from the tester.py file:
