Spring靴中的阴影罐

Question

我试图在spring boot应用程序中构建shaded jar，但是遇到了一些问题。我不知道我做错了什么。我还阅读了以下链接，但没有运气maven-shade-plugin错误:无法在org . Apache . maven . plugins . shade . resource . manifestresourceformer中找到“resource”的setter、adder或field

这是我的Pom.xml

当我运行mvn包时，我在控制台上得到了以下异常

场景是：我有两个Spring启动项目，并且都有相同的类型，可执行jar。我正在此项目中添加其他项目作为依赖项。这就是为什么我正在构建一个具有所有依赖项的罐子。

有什么建议吗？

Answer 1

我不知道为什么，但它对我有用。仅使用

<transformer    implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
    <manifestEntries>
        <Main-Class>com.text.dashboard.hello.Application</Main-Class>
    </manifestEntries>
</transformer>

代替

 <transformers>
     <transformer    implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
         <manifestEntries>
             <Main-Class>com.text.dashboard.hello.Application</Main-Class>
         </manifestEntries>
     </transformer>
</transformers>
