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

Question

我执行“mvn clean package”，它使用snapshot.jar 创建一个压缩文件（基于我的assembly.xml），然后创建压缩文件，最后创建jar-with-dependencies.jar

我认为因为 zip 文件是在创建 jar-with-dependencies.jar 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，如何强制在调用组装目标之前先构建 jar-with-dependencies，以便所有 jar复制到压缩文件）

这里是 pom.xml

您绝对可以将single 目标分成两个执行（参见https://stackoverflow.com/a/8726969/3114959 或https://stackoverflow.com/a/15799254/3114959）。
Maven 按照它们在有效 pom 中出现的顺序执行事物（只要属于同一阶段），所以如果你指定两个执行分开，你应该没问题。

<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 ---

后一个执行（make-the-zip）肯定可以包含前一个（create-jar-with-dependencies）的结果。
