Question

我无法在eclipse中生成querydsl Q类。如果有人有任何帮助，将不胜感激。以下是我尝试过的方法和我的pom.xml文件中的片段

我已经复制了位于此处的建议插件设置：

https://github.com/querydsl/apt-maven-plugin/wiki/m2e-usage

M2E and having maven generated source folders as eclipse source folders

我确保安装了Maven并将我的eclipse .ini文件更改为运行JDK，如下所述：

You need to run build with JDK or have tools.jar on the classpath Eclipse issue with Maven build and JDK when generating Qclasses in Querydsl Eclipse issue with Maven build and JDK when generating Qclasses in Querydsl

我已经转到项目文件夹并运行了mvn generate-sources并将该文件夹添加到了类路径中。仍然，项目找不到生成的任何Q类，我在目标文件夹中看不到任何生成。如果有人有任何见解，我将非常感激。感谢

Answer 1

QueryDsl生成到文件夹target/generated-sources/java中，但是您将target/generated-sources添加为源文件夹。

<outputDirectory>target/generated-sources/java</outputDirectory>

vs

<classpathentry kind="src" path="target/generated-sources"/>

Answer 2

尝试将此设置为eclipse.ini文件并重新启动eclipse以确保它也使用您的JDK：

-vm
C:\jdk1.7\bin\javaw.exe

注意事项：这必须高于-vmargs 你的VM的完整路径可能与上面的那个不同

OR

进入运行配置并设置VM参数

-vm {path to jdk javaw.exe}

eclipse中的Querydsl没有在maven项目中生成查询类型类
