Question

我使用Maven为ide intellij创建了一个java应用程序，包括几个依赖项（特别是OrientDb和Bouncy Castle）。

应用程序与ide正常工作，但我需要使用ssh在另一台计算机上运行它。所以使用Maven Assembly Plugin（http://maven.apache.org/plugins/maven-assembly-plugin/usage.html）我制作了一个可执行jar。但是当我运行它时，我得到了这个错误：

我该怎么做才能解决这个问题？我也对其他构建解决方案持开放态度，但我对Java / Maven不是很有经验。

这是我的pom.xml文件：

我把那个过滤器修复了这个错误：

Exception in thread "main" java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

但我得到的错误与以前完全相同：

Answer 1

我找到了解决问题的方法。

事实是我只需要包的orientdb-core而不是所有的orientdb-graph。将maven依赖关系更改为

<dependency>
            <groupId>com.orientechnologies</groupId>
            <artifactId>orientdb-core</artifactId>
            <version>2.1.15</version>
</dependency>

让奇怪的异常消失了！

Answer 2

问题是META-INF /服务中的JAVA服务。它们未合并到您的可执行文件中。因此，某些执行程序未正确注册。您应该使用maven shade插件来构建jar并使用资源转换器

https://maven.apache.org/plugins/maven-shade-plugin/examples/resource-transformers.html

用IntelliJ制作OrientDB可执行jar
