Maven Assembly 插件不会将 jar-with-dependencies 复制到 zip 文件

Question

我做了 "mvn clean package"，它使用 snapshot.jar 创建了一个 zip 文件（基于我的 assembly.xml），然后创建了 zip 文件，最后创建了 jar-with-dependencies.jar

我想因为 zip 文件是在 jar-with-dependencies.jar 创建之前创建的，所以它从未被复制到 zip 文件中。

如何强制 maven 将 snapshot.jar 和 jar-with-dependencies.jar 复制到 zip 文件中（换句话说，我如何强制 jar-with-dependencies 在调用组装目标之前首先构建这样所有的 jar 都会被复制到 zip 文件中）

这里是pom.xml

您绝对可以将 single 目标分成两个执行（参见 or ）。
Maven 的执行顺序与它们在 effective pom 中出现的顺序相同（只要它们属于同一阶段）所以如果您指定两个执行分开，您应该没问题。

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-assembly-plugin</artifactId>
            <executions>
                <execution>
                    <id>create-jar-with-dependencies</id>
                    <goals>
                        <goal>single</goal>
                    </goals>
                    <phase>package</phase>
                    <configuration>
                        <descriptorRefs>
                            <descriptorRef>jar-with-dependencies</descriptorRef>
                        </descriptorRefs>
                    </configuration>
                </execution>
                <execution>
                    <id>make-the-zip</id>
                    <goals>
                        <goal>single</goal>
                    </goals>
                    <phase>package</phase>
                    <configuration>
                        <descriptors>
                            <descriptor>src/main/assembly/assembly.xml</descriptor>
                        </descriptors>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

因此，您将在构建期间看到 2 次执行：

[INFO] --- maven-assembly-plugin:2.2-beta-5:single (create-jar-with-dependencies) @ artid ---
[INFO] ... some more output ...
[INFO] --- maven-assembly-plugin:2.2-beta-5:single (make-the-zip) @ artid ---

后面的执行（make-the-zip）肯定可以包含前者（create-jar-with-dependencies）的结果。

Maven Assembly 插件不会将 jar-with-dependencies 复制到 zip 文件
