用于salesforce API jar的Maven shaded jar中的java.lang.NoClassDefFoundError

Question

我有一个Apache Maven Java项目，它导入类：

com.sforce.soap.enterprise.EnterpriseConnection

当从IntelliJ运行项目时，我在执行代码时没有任何问题。但是，我希望能够从命令行作为阴影JAR运行项目。我一直在用“MVN包”对罐子进行着色。当我从命令行运行jar时，我会得到错误：

<dependency>
  <groupId>qa-integration.sfdc</groupId>
  <artifactId>enterprise</artifactId>
  <version>1.0.0</version>
  <scope>system</scope>
  <systemPath>${project.basedir}/libs/enterprise-1.0.0.jar</systemPath>
</dependency>
<dependency>
  <groupId>qa-integration.sfdc</groupId>
  <artifactId>metadata</artifactId>
  <version>1.0.0</version>
  <scope>system</scope>
  <systemPath>${project.basedir}/libs/metadata-1.0.0.jar</systemPath>
</dependency>

我遇到了这个问题，我的解决方案是将以下代码段添加到我的pom.xml中：

<build>
            <plugins>
                <plugin>
                    <artifactId>maven-assembly-plugin</artifactId>
                    <configuration>
                        <archive>
                            <manifest>
                                <mainClass>corrigo.Main</mainClass>
                            </manifest>
                        </archive>
                        <descriptorRefs>
                            <descriptorRef>jar-with-dependencies</descriptorRef>
                        </descriptorRefs>
                    </configuration>
                    <executions>
                        <execution>
                            <id>make-assembly</id> <!-- this is used for inheritance merges -->
                            <phase>package</phase> <!-- bind to the packaging phase -->
                            <goals>
                                <goal>single</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
                <!--<plugin>-->
                    <!--<groupId>org.apache.maven.plugins</groupId>-->
                    <!--<artifactId>maven-jar-plugin</artifactId>-->
                    <!--<version>2.4</version>-->
                    <!--<configuration>-->
                        <!--<archive>-->
                            <!--<manifest>-->
                                <!--<mainClass>corrigo.Main</mainClass>-->
                            <!--</manifest>-->
                        <!--</archive>-->
                    <!--</configuration>-->
                <!--</plugin>-->
            </plugins>
        </build>

然后您只需运行MVN包。下面是一个可靠的资源：https://www.mkyong.com/maven/how-to-create-a-jar-file-with-maven/
