Question

    <plugin>
        <artifactId>maven-assembly-plugin</artifactId>
        <configuration>
            <descriptorRefs>
                <descriptorRef>jar-with-dependencies</descriptorRef>
            </descriptorRefs>
            <archive>
                <manifest>
                    <mainClass>com.company.Main</mainClass>
                </manifest>
            </archive>
        </configuration>
        <executions>
            <execution>
                <phase>package</phase>
                <goals>
                    <goal>single</goal>
                </goals>
            </execution>
        </executions>
    </plugin>

问题是我想在项目中保留一些本地依赖项。

我在pom.xml中定义了它们，如此：

    <dependency>
        <groupId>groupid</groupId>
        <artifactId>local</artifactId>
        <version>1.1</version>
        <scope>system</scope>
        <systemPath>${basedir}/lib/local-utilities-1.1.jar</systemPath>
    </dependency>

现在当我打包整个事件maven-assembly-plugin时，只打包自动下载并在repo中可用的依赖项...这可能是因为那些本地JAR在编译阶段可用，而不是在包阶段（正确吗？）。

如何让这个插件包含那些依赖项呢？我尝试将<scope>更改为package和其他阶段，但显然Maven不允许这样做。

您需要“手动”复制这些依赖项，以便打包程序可以包含它们。

使用maven-assembly-plugin和本地依赖项
