Maven uber(fat) jar

如何解决Maven uber(fat) jar

我有一个 Swing GUI 应用程序使用 maven 作为依赖管理器。它使用一个依赖项（我可以访问源代码，我可以修改它）：

    <dependency>
        <groupId>tr.com.bermuda.bsign</groupId>
        <artifactId>bsignclient</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>

此依赖项生成线程，我使用实现 SwingWorker 类的 Runnable 调用它。

这是我的工作 pom.xml 文件：

<?xml version="1.0" encoding="UTF-8"?>

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

当我执行 mvn clean package 时，进入目标文件夹，将 libs 文件夹和我的 jar 复制到另一个文件夹（我们称之为试用文件夹）然后在试用文件夹中执行 java -jar bsignclient.jar，我可以使用依赖项的方法，它工作正常。

我尝试了 maven-shade 和 maven-assembly 插件，我的 gui 应用程序可以运行，但无法运行依赖项的方法。这是我的 shade 插件（取自 mkyong）：

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-eclipse-plugin</artifactId>

                    <downloadJavadocs>false</downloadJavadocs>
                </configuration>
            </plugin>

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>

                <execution>
                <phase>package</phase>
                <goals>
                    <goal>shade</goal>
                </goals>
                <configuration>
                    <transformers>
                        <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                        <mainClass>com.bermuda.App</mainClass>
                    </transformer>
                    </transformers>
                </configuration>
                    </execution>
                </executions>
            </plugin>

当我尝试访问我的依赖项时，它给出了这个异常：

我怎样才能让我的罐子变成一个胖罐子？
