使用 Netbeans 清理和构建 Maven 项目 - 编译失败

【问题标题】：Clean and Build a Maven Project with Netbeans - Compilation failure使用 Netbeans 清理和构建 Maven 项目 - 编译失败
【发布时间】：2014-11-27 03:11:57
【问题描述】：

我已经准备好部署我的项目，所以我需要创建一个可执行的 jar 来进行分发。在线阅读后，我现在尝试clean and build我的项目（ProjectMaven），它是一个具有依赖关系的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

阅读this 和this 的答案后，我将pom.xml 文件设为：

com.dazito.retro.eventbus 是我创建的另一个 Maven 项目，该项目依赖于该项目。

这是我在项目 (ProjectMaven) 上按 Clean and Build 时 Maven 创建的输出。

To see the full stack trace of the errors, re-run Maven with the -e switch.
Re-run Maven using the -X switch to enable full debug logging.

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 netbeans 中按下运行按钮时会执行罚款。

【问题讨论】：

  • 看起来像这样com.dazito.retro.eventbus.buses.singletons cass 未找到。让你的它没有拼写错误，并且相关的 jar 在你的类路径中
  • 您需要在构建 pom 中定义它，这意味着您的项目必须由本地文件夹路径定义或在 maven repo 中定义，以便它可以根据它构建其他应用程序

我不知道这个插件有多好，但你可能想考虑一下。

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

【讨论】：

  • 哇，太棒了！这就像一颗子弹杀死两只鸟。谢谢！现在唯一的问题是双击生成的 .exe 文件时没有任何反应。使用命令行也没有任何反应，不会生成任何输出。你知道为什么吗？
  • 我发现问题在于我的应用程序中的图像，有些东西没有正确加载它们。我收到了这个例外：Could not load the icon: /images/view-refresh.png Exception in thread "main" java.lang.NullPointerException。如果我删除它加载的图像就好了。谢谢！
  • 它会创建 .exe 文件，但是当我们双击 .exe 文件时，什么也没有发生。构建没有错误。
【解决方案2】：

dazito，如果图像没有加载，那么我想你必须检查路径。我可以看到路径是相对的，而不是绝对的。
