(I am using Windows.)
I am trying to run maven from a python script. I have this:
import subprocessmvn="C:\\_home\\apache-maven-2.2.1\\bin\\mvn.bat --version"
p = subprocess.Popen(mvn, shell=True, stdout = subprocess.PIPE)stdout, stderr = p.communicate()
print p.returncode # is 0 if success
It works fine, but I am wondering about the following:
- Better ways to add parameters instead of appending the string.
- Maybe some specific way to run maven without the above.
- A way to show the output (currently it only prints a 1 or 0 based on failure/success).
What I am trying to accomplish long term (I note this in case someone has a better method) is to make a simple script to build a list of projects and move another list of files (jars/other modified things) to a folder to deploy to VMs, it's a huge pain to do manually. I have this working in a batch script no sweat, I am just curious to learn Python and wonder if it'd be easier to manage because I could just make a couple of lists and iterate over each of the locations rather than have a line for each task in the batch script.
(Short version of what my batch script looks like.)
