问题描述
我有一个shell脚本，启动一个Maven的exec：java程序 -
I have a shell script that launches a Maven exec:java process -
exec mvn exec:java -Dexec.mainClass=... -Dexec.args="$*"
现在可悲的是，如果我跑
Now sadly if I run
./myMagicShellScript arg1 "arg 2"
单串 ARG 2 不让它通过一样，我想一个参数。
the single string arg 2 doesn't make it through as a single argument as I'd like.
有什么想法就如何逃生/通过传递正确的事情（perferably以干净的方式）？
Any thoughts as to how to escape / pass things through properly (perferably in a clean way)?
推荐答案
我接过一看<一个href=\"http://svn.apache.org/viewvc/maven/maven-2/branches/maven-2.2.x/apache-maven/src/bin/mvn?view=markup\"相对=nofollow> MVN 脚本，并做了一些测试。这是我想出了：
I took a look at the mvn script and did some testing. This is what I came up with:
试着改变你的脚本是这样的：
Try changing your script to look like this:
args=(${@// /\\ })
exec mvn exec:java -Dexec.mainClass=... -Dexec.args="${args[*]}"
这改变了这是每个数组元素中的所有空格用反斜杠转义。
That changes all spaces which are within each array element to be escaped with a backslash.
