Question

我正在尝试使用Xtend生成并运行导出的Eclipse RCP应用程序。我正在将Windows 10与Java 1.8.0_181和Eclipse Photon一起使用。

以下步骤将在我可以创建的干净环境中重新创建问题：

使用Oomph的高级模式安装Eclipse Photon
- 控制池的位置，以免其他Eclipse用法无意中破坏池。
- 确保Java 8用于Eclipse
使用以下配置创建一个新的Eclipse工作区：
- PDE将运行时文件存储在工作空间的单独部分中
- 已安装完整的Xtext SDK
使用以下属性创建Eclipse插件项目：
- 创建一个RCP应用程序
- 使用Eclipse E4应用程序模板为项目添加种子
- 包括可选生成的图形组件
- 将生成的Java文件转换为Xtend并摆脱原始Java文件。
- 加载生成的产品配置，然后从“概述”页面运行该应用程序。这没有问题。
- 使用产品配置页面中的导出向导导出项目。导出运行时没有报告任何错误。
- 从命令行启动导出的项目。它以以下方式失败：
- 应用程序启动，但Xtend代码提供的所有组件均未显示。
- 这是运行中的日志：

- As you can see none of the classes specified in the Xtend files could be found. It appears that the reason for this that the jar file containing the project artifacts (in the exported plugins directory) only contains the Xtend source code, not the Java .class files that I believe are needed.

我已经添加了Eclipse生成的build.properties文件。我没有碰它。

source.. = src/
output.. = bin/
bin.includes = plugin.xml,\
               META-INF/,\
               .,\
               icons/,\
               css/default.css,\
               Application.e4xmi

我需要怎么做才能为项目获取正确的导出jar文件？

Answer 1

您需要确保xtend-gen文件夹是源文件夹并且在build.properties文件中列出。您甚至应该收到警告。

及之后

source.. = src/,\
       xtend-gen/
output.. = bin/
bin.includes = META-INF/,\
...
               .

，这里是将xtend-gen添加为源文件夹的.classpath

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8"/>
    <classpathentry kind="con" path="org.eclipse.pde.core.requiredPlugins"/>
    <classpathentry kind="src" path="src"/>
    <classpathentry kind="src" path="xtend-gen"/>
    <classpathentry kind="output" path="bin"/>
</classpath>
