java - Maven Assembly 插件父描述符共享

Question

我有一个项目，有一个父模块。父级和子级都使用 maven-assemble-plugin。

父级使用它自己的描述符(zip.xml):

<?xml version="1.0" encoding="UTF-8"?>
<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.0.xsd">
    <id>bin</id>
    <includeBaseDirectory>false</includeBaseDirectory>
    <formats>
        <format>zip</format>
    </formats>
    <fileSets>
        <fileSet>
            <directory>${svn.scripts}</directory>
            <includes>
                <include>query.*</include>
            </includes>
        </fileSet>
        <fileSet>
            <directory>${cfgreader.dist}</directory>
            <includes>
                <include>*.jar</include>
            </includes>
        </fileSet>
    </fileSets>
</assembly>

这样:

<build>
    <plugins>
        <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <configuration>
                <descriptor>${basedir}/descriptors/zip.xml</descriptor>
                <finalName>${patch.prefix}_rev</finalName>
                <appendAssemblyId>false</appendAssemblyId>
            </configuration>
            <executions>
                <execution>
                    <id>make-assembly</id>
                    <phase>package</phase>
                    <goals>
                        <goal>single</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

而我 child 的模块 pom.xml 有:

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-assembly-plugin</artifactId>
        <configuration>
            <archive>
                <manifest>
                    <mainClass>com.test.cfgReader</mainClass>
                </manifest>
            </archive>
            <descriptorRefs>
                <descriptorRef>jar-with-dependencies</descriptorRef>
            </descriptorRefs>
            <finalName>cfgreader</finalName>
            <appendAssemblyId>false</appendAssemblyId>
        </configuration>
        <executions>
            <execution>
                <id>make-assembly</id>
                <phase>package</phase>
                <goals>
                    <goal>single</goal>
                </goals>
            </execution>
        </executions>
    </plugin>

问题是子模块尝试使用 zip.xml 描述符并导致错误:

.... 如果我从父 pom.xml 中删除 maven-assemble-plugin 一切都很好，如果我再次添加，父任务工作正常，而子任务失败。如何禁用描述符传播到 child ？

Answer 1

首先创建一个单独的模块，例如 mod- assembly ，并将 maven-assemble-plugin 的所有描述符和配置放入该模块中，并使此 mod- assembly 和您的父级的其他子级。除此之外，使用更新版本的 maven- assembly-plugin (2.4 而不是 2.2-beta-5)。
