使用ant构建xtext项目时出错：语法类的生成失败

时间：2012-04-09 20:26:15

标签： ant grammar xtext temp

我正在为我的学士论文开发一个eclipse插件项目。

我想在运行时使用执行Mwe2Launcher类的ant脚本执行'Generate Xtext Artifacts'，并在temp文件夹中进行生成。

我写了一个Activator来在temp文件夹中创建一个项目文件夹并复制mwe2文件，我的语法文件和ant脚本。

执行Ant脚本会导致此错误：

还没有生成未映射的“.java”文件。缺少整个“/src-gen/...../foobar/foo”文件夹。

我想这就是原因，应该修复什么。

我真的不知道，问题出在哪里。我已经在Eclipse forum进行了讨论，你可以在那里找到build.xml但是对于另一个项目，还有一个Activator类来激活插件并执行复制并执行ant脚本，你也找到了mwe2文件我用。

答案 0 :(得分：1)

您必须确保在工作流程中将临时文件夹注册为平台URI。 Xtext使用EMF的平台：/ resource URI方案。因此，必须注册平台根，以便根据平台路径定义从文件系统上的绝对位置到逻辑位置的路径映射。您也可以尝试复制.project文件。我认为如果你已经将temp文件夹注册为平台路径，这将有所帮助。
