Maven: 如何从命令行更改路径到目标目录？

You should use profiles.

<profiles>
<profile>
<id>otherOutputDir</id>
<build>
<directory>yourDirectory</directory>
</build>
</profile>
</profiles>

And start maven with your profile

mvn compile -PotherOutputDir

If you really want to define your directory from the command line you could do something like this (NOT recommended at all) :

<properties>
<buildDirectory>${project.basedir}/target</buildDirectory>
</properties>


<build>
<directory>${buildDirectory}</directory>
</build>

And compile like this :

mvn compile -DbuildDirectory=test

That's because you can't change the target directory by using -Dproject.build.directory

Colin is correct that a profile should be used. However, his answer hard-codes the target directory in the profile. An alternate solution would be to add a profile like this:

    <profile>
<id>alternateBuildDir</id>
<activation>
<property>
<name>alt.build.dir</name>
</property>
</activation>
<build>
<directory>${alt.build.dir}</directory>
</build>
</profile>

Doing so would have the effect of changing the build directory to whatever is given by the alt.build.dir property, which can be given in a POM, in the user's settings, or on the command line. If the property is not present, the compilation will happen in the normal target directory.
