Question

我的项目准备好部署，所以我需要创建一个可执行jar来分发。在线阅读后，我现在尝试clean and build我的项目（ProjectMaven），这是一个带有依赖关系的Maven项目（在Netbeans 8上）

我的项目依赖于我使用Maven

创建的另一个项目

在阅读this和this个答案后，我已经制作了pom.xml这样的文件：

com.dazito.retro.eventbus是我创建的另一个Maven项目，该项目取决于该项目。

我做错了什么？我该如何解决这个问题，以便我可以清理和构建项目？该项目没有编译错误，并且在按netbeans中的运行按钮时执行罚款。

我不太了解这个插件，但你有可能想要考虑。

使用shade插件代替程序集插件。 http://maven.apache.org/plugins/maven-shade-plugin/

Answer 2

dazito，如果未加载图像，那么我想您必须检查路径。如我所见，路径是相对的而不是绝对的。
