Maven Shade插件无法替换原始jar文件

Question

我的maven-shade-plugin没有用阴影Jar替换原始的Jar，感觉很奇怪。有人知道可能是什么原因吗？

这是我在pom.xml中的插件：

你目前的设置是否在常规JAR旁边创建了带阴影的JAR？当你执行'mvn package'时，你是否看到插件在运行？ pom XML标签封装<plugin>定义是<plugins>还是<pluginManagement>？ - Karol Dowbecki

我可以在Maven日志中看到maven-shade-plugin被执行。 - zjffdu

请添加 mvn -X clean package 的输出，并回答我提出的其他问题。 - Karol Dowbecki

Answer 1

默认情况下，Shaded插件将原始文件保存为-original.jar。如果您想用新生成的（阴影化的）文件替换原始文件，请在配置插件部分中添加此行：

<configuration>
    ...

    <outputFile>${output.directory}\${project.artifactId}-${project.version}.jar</outputFile>
    ...
</configuration>

用你的阴影插件 outputDirectory 替换 output.directory。

看起来 Configuration 标签应该在层次结构中放在 execution 标签内部，如下所示。请重新组织 executions 和 execution 标签，并将您的配置包含在其中，如下所示。

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-shade-plugin</artifactId>
                <version>${maven.shade.plugin}</version>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>shade</goal>
                        </goals>
                        <configuration>
                            <relocations>
                                <relocation>
                                    <pattern>org.apache*</pattern>
                                    <shadedPattern>shaded.org.apache*</shadedPattern>
                                </relocation>
                                <relocation>
                                    <pattern>com.cookie*</pattern>
                                    <shadedPattern>shaded.com.cookie*</shadedPattern>
                                </relocation>
                            </relocations>

                        </configuration>
                    </execution>
                </executions>

            </plugin>

        </plugins>
