You should use profiles.
您应该使用配置文件。
<profiles>
<profile>
<id>otherOutputDir</id>
<build>
<directory>yourDirectory</directory>
</build>
</profile>
</profiles>
And start maven with your profile
并使用您的个人资料启动 Maven
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) :
如果你真的想从命令行定义你的目录，你可以做这样的事情（根本不推荐）：
<properties>
<buildDirectory>${project.basedir}/target</buildDirectory>
</properties>
<build>
<directory>${buildDirectory}</directory>
</build>
And compile like this :
并像这样编译：
mvn compile -DbuildDirectory=test
That's because you can't change the target directory by using -Dproject.build.directory
那是因为你不能通过使用改变目标目录 -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:
Colin 是正确的，应该使用配置文件。但是，他的回答对配置文件中的目标目录进行了硬编码。另一种解决方案是添加这样的配置文件：
<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.
这样做的效果是将构建目录更改为由 alt.build.dir 属性给出的任何内容，该属性可以在 POM、用户设置或命令行中给出。如果该属性不存在，则编译将在普通目标目录中进行。

My solution:
我的解决方案：
in pom.xml:
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <version>2.3.2</version> <configuration> <outputDirectory>${dir}</outputDirectory> </configuration> </plugin>command in bash:
mvn package -Ddir="/home/myuser/"
在 pom.xml 中：
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <version>2.3.2</version> <configuration> <outputDirectory>${dir}</outputDirectory> </configuration> </plugin>bash 中的命令：
mvn package -Ddir="/home/myuser/"
