问题
我正在尝试在我们的超级pom中定义一个属性，它将被所有子项目用作生成的工件的目标。
为此，我考虑使用project / build / finalName但这似乎不起作用，即使对于简单的poms：
Command
mvn archetype:create \
-DarchetypeGroupId=org.apache.maven.archetypes \
-DgroupId=com.mycompany.app \
-DartifactId=my-app
POM
maxim@maxim-desktop:/tmp/mvn_test$ cat my-app/pom.xml

我希望字符串"testing"会出现在生成的工件名称的某处。
我误解了"finalName"的目的吗？
谢谢你，马克西姆。

你在插件配置部分中设置了finalName属性：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<finalName>myJar</finalName>
</configuration>
</plugin>
如official documentation所示。
更新：对于Maven> = 3
基于Matthew's的评论你现在可以这样做：
<packaging>jar</packaging>
<build>
<finalName>WhatEverYouLikey</finalName>
</build>

@格言
尝试这个...
pom.xml
<groupId>org.opensource</groupId>
<artifactId>base</artifactId>
<version>1.0.0.SNAPSHOT</version>
..............
<properties>
<my.version>4.0.8.8</my.version>
</properties>
<build>
<finalName>my-base-project</finalName>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<version>2.3.1</version>
<executions>
<execution>
<goals>
<goal>install-file</goal>
</goals>
<phase>install</phase>
<configuration>
<file>${project.build.finalName}.${project.packaging}</file>
<generatePom>false</generatePom>
<pomFile>pom.xml</pomFile>
<version>${my.version}</version>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
Commnadmvn clean install
输出

所有提供的答案都比必要的更复杂。假设你正在构建一个jar文件，你需要做的就是将a<jar.finalName>tag添加到your<properties>section：
<properties>
<jar.finalName>${project.name}</jar.finalName>
</properties>
这将生成一个jar：
project/target/${project.name}.jar
这是在documentation-注意到User Property：
finalName:
Name of the generated JAR.
Type: java.lang.String
Required: No
User Property: jar.finalName
Default: ${project.build.finalName}
###命令行用法
你还应该能够在命令行上使用此选项：
mvn -Djar.finalName=myCustomName ...
你应该得到myCustomName.jar，虽然我还没有测试过。
