使用帶有groovy-eclipse-compiler的querydsl-maven-plugin生成QueryDsl類

Question

我正在嘗試使用此處描述的替代方法從groovy實體生成querydsl類http://www.querydsl.com/static/querydsl/2.7.3/reference/html/ch03s02.html

我面臨的問題是這些類僅在我兩次執行mvn編譯/打包時才生成

即有順序的東西，類應該在編譯groovy類之前生成

否則我得到編譯錯誤

Groovy:unable to resolve class com.application.domain.QUser

我的pom.xml

我想念的是什么？

Answer 1

你需要：

1. 編譯源Groovy代碼
2. 后處理類以生成QClass

3. 再次編譯生成的QClass。
