Question

我有以下问题。我有一个多模块项目。我想在顶层pom上运行maven-assembly插件，它也是其模块的父pom。我希望插件只在顶级pom上执行。目前它还尝试在所有子模块上执行。我不想要这个，因为我只需要从一个地方（顶层目标目录）获取所有模块和子模块的所有源代码。

这是我的描述符：

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd">
<id>src</id>
<formats>
    <format>zip</format>
</formats>
<moduleSets>
    <moduleSet>
        <includeSubModules>true</includeSubModules>
        <sources>
            <useDefaultExcludes>true</useDefaultExcludes>
            <includeModuleDirectory>false</includeModuleDirectory>
            <fileSets>
                <fileSet>
                    <outputDirectory>/</outputDirectory>
                    <useDefaultExcludes>true</useDefaultExcludes>
                    <includes>
                        <include>src/main/**</include>
                        <include>src/test/**</include>
                        <include>target/classes/**</include>
                    </includes>
                </fileSet>
            </fileSets>
        </sources>
    </moduleSet>
</moduleSets>

pom文件如下所示：

<?xml version="1.0"?>
<project
      xmlns="http://maven.apache.org/POM/4.0.0"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"
      >

    <module>6</module>
</modules>

        <version>4.8.2</version>
        <scope>compile</scope>
    </dependency>
</dependencies>
</project>

父pom只包含一些我希望在所有模块中继承的依赖项。子模块将当前pom作为父级。现在，如果我跑：

mvn assembly：single -Ddescriptor = somedes.xml

它在顶级pom上运行正常并收集我需要的所有资源。但它不会停止并开始在所有子项目上执行此目标，当然也没有为此定义描述符。如何强制执行仅在顶层pom上？

我试图添加：

-Dexecution.inherited = false

但它没有帮助。添加

-Dassembly.ignoreMissingDescriptor = true

也没有帮助。有什么想法吗？

Answer 1

将其放入父pom中的maven-assembly-plugin的配置中。

<runOnlyAtExecutionRoot>true</runOnlyAtExecutionRoot>

Answer 2

你是对的，你试图使用param "-Dexecution.inherited=false"。

我在子模块的pom.xml中通过xml标签<inherited>false</inherited>定义了非继承，它似乎有效。

Answer 3

-Dassembly.runOnlyAtExecutionRoot =真

这是使其按照描述工作的属性。

Answer 4

不确定我是否了解情况。但要禁用插件的执行，请尝试以下操作：

        <!-- Don't run the reporting tool in submodule. -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-antrun-plugin</artifactId>
            <executions combine.self="override" combine.>
                <execution><id>reporting</id><phase>none</phase></execution>
            </executions>
        </plugin>

您需要知道来自父级的执行ID并将其放入此代码段....

这是一个很好的明确解释：http://www.sonatype.com/people/2011/01/maven-how-to-merging-plugin-configuration-in-complex-projects/

Answer 5

您可以在maven阶段无中禁用maven-assembly-plugin。

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-assembly-plugin</artifactId>
  <version>2.5</version>
  <executions>
    <execution>
      <phase>none</phase>
      <goals>
        <goal>single</goal>
      </goals>
    </execution>
  </executions>
</plugin>
