我正在为使用XText 2.0的项目寻找一个示例pom.xml
,尤其是“普通”maven项目中的代码生成器XP和1.1。
我已经花时间与谷歌合作,但我可能会使用错误的术语,或者没有例子。
我已经为xtext 0.7.2工作了pom,我想将项目更新为2.0。但我不知道从哪里开始。 我目前所拥有的是4个maven项目的结构:
mydsl项目是xtext 0.7.2项目和(mydsl
)中的附加pom,它们将生成的类提供为maven依赖项。
application
有一个mwe
工作流程和xpand模板来生成源代码。该项目与mydsl
因为我没有实现如此多的gui编辑器功能,所以我甚至会抛弃所有的xtext东西(除了语法和xpand模板)并构建一个全新的xtext 2项目。
但我真的没有胶水如何为(新)mydsl项目建造pom。
答案 0 :(得分:2)
我找到了真正的maven xtext2项目。
答案 1 :(得分:1)
最棘手的部分之一是在XText2语法项目中,xtend-gen
文件夹中的文件名为<<project>>Generator.java
。该文件不是由Generate<<project>>.mwe2
工作流创建的,而是由一些eclipse魔法创建的。但是编译代码需要这个文件!
所以我的解决方案是让eclipse生成该文件,然后将其添加到svn,就像任何普通的手写类一样。
然后只需要将这个pom添加到项目中。所以maven也会启动工作流程。
但是有一个缺点:工作流还为邻居项目.ui
和.test
生成类,因此它需要清单文件。为了克服maven发布插件的麻烦,可以添加一个父maven项目,其中包含语法项目和两个假人.ui
和.test
包含xtext语法的项目的Pom:

使用grammer和dsl生成源代码的项目的POM。这与xtext 0.7.1几乎相同。但有一点不同。 mwe文件中使用的MweReader
不再退出(因为xtext 1.0.1)因此需要使用org.eclipse.xtext.mwe.Reader
。此读取器不再将模型文件作为输入,而是文件的路径。它还将它存储在一个所谓的“槽”中。但是这个插槽是一个元素列表。因此,需要更改:FOR
中的<expand value="templates::Main::main FOR model"/>
到FOREACH
