从Python脚本运行Maven的方法? [英] Way to run Maven from Python script?

问题描述

(我正在使用Windows.)

我正在尝试从python脚本运行maven.我有这个:

I am trying to run maven from a python script. I have this:

import subprocess

mvn="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

它工作正常，但我想知道以下内容:

It works fine, but I am wondering about the following:

• 添加参数而不是附加字符串的更好方法.
• 也许是不使用上述方法运行maven的某些特定方法.
• 一种显示输出的方式(当前，它仅根据失败/成功而输出1或0).

我要长期完成的工作(如果有人有更好的方法，请注意这一点)是制作一个简单的脚本来构建项目列表并将另一文件列表(罐子/其他修改过的东西)移动到文件夹部署到虚拟机，手动完成是一个巨大的痛苦.我可以不费吹灰之力地在批处理脚本中工作，我只是好奇地学习Python，想知道它是否更容易管理，因为我可以列出几个列表并遍历每个位置，而不用一行批处理脚本中的每个任务.

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.

(我的批处理脚本的简短版本.)

@set version=7.8.3
@set staging_folder=C:\Users\me\Desktop\staging

@set stage_was=%staging_folder%\was
@set stage_ear=%stage_was%\stuffui.ear
@set stage_war=%stage_ear%\stuff-%version%.war

:: delete stage contents
call del /s /q %staging_folder%
call rmdir /s /q %stage_was%

:: make folders
call mkdir %stage_ear%
call mkdir %stage_war%\WEB-INF\lib

:: maven builds
call mvn -f C:\workspace\pom.xml -pl proj1,proj2 clean install

:: copy to stage
call xcopy C:\workspace\proj1\target\thing1.jar %stage_ear%\ /i /y

call xcopy C:\workspace\proj2\target\thing2.jar %stage_ear%\ /i /y
call xcopy C:\workspace\proj2\target\thing2.jar %stage_war%\WEB-INF\lib\ /i /y

推荐答案

有 Mark对使用Python访问Java API信息 的回答提到:

Mark's answer to Accessing Java API information with Python mentions:

Jython ，它是在Java VM上运行的Python.

Jython which is Python run on the Java VM.
