将选项从Gradle传递给JPAAnnotationProcessor [英] Pass options to JPAAnnotationProcessor from Gradle

问题描述

我有一个Gradle任务，它使用Querydsl JPAAnnotationProcessor从注释中生成JPA查询类型源文件。我正在使用一个Gradle任务，它非常类似于joeG在从Gradle构建脚本生成JPA2元模型。

我能够生成源文件，但是我想排除某些文件一定的包装。 Querydsl文档列出了querydsl.excludedPackages选项。如何将此选项传递给Gradle中的JPAAnnotationProcessor？

在Maven中，我可以使用apt-maven-plugin并在配置中传递如下内容：

 < options> 
< querydsl.excludedPackages> com.thomsonreuters.domainmodel.eventhistory< /querydsl.excludedPackages> 
< / options> 
  

但我无法弄清楚如何使用Gradle来做到这一点。

我现在使用这个 build.gradle 脚本来生成QueryDSL类型：

  project（my-project）{
 
 sourceSets {
 generated {
 java {
 srcDir'src / main / generated'
} 
} 
} 
 
配置{
 querydslapt 
} 
 
依赖项{
 //您的依赖项
 querydslaptcom.mysema.querydsl：querydsl-apt：3.4.0
} 
 
任务generateSources（type ：JavaCompile，group：'build'，description：'生成QueryDSL查询类型'）{
 source = sourceSets.main.java $ b $ classpath = configurations.compile + configurations.querydslapt 
 options。 compilerArgs = ['-proc：only'，
'-processor '，
'com.mysema.query.apt.jpa.JPAAnnotationProcessor'，
'-Aquerydsl.excludedPackages = com.thomsonreuters.domainmodel.eventhistory'] 
 options.warnings = false 
 destinationDir = file（'src / main / generated'）
 outputs.dir destinationDir 
} 
 
 compileJava.source generateSources.outputs.files 
 
 clean {
 delete sourceSets.generated.java.srcDirs 
} 
 
} 
  

I have a Gradle task that uses the Querydsl JPAAnnotationProcessor to generate JPA query type source files from annotations. I am using a Gradle task very similar to the one in the response by joeG in the post Generating JPA2 Metamodel from a Gradle build script.

I am able to generate the source files, but I would like to exclude some files in a certain package. The Querydsl documentation lists the querydsl.excludedPackages option. How can I pass this option to the JPAAnnotationProcessor in Gradle?

In Maven I can use the apt-maven-plugin and in the configuration pass something like:

<options>
<querydsl.excludedPackages>com.thomsonreuters.domainmodel.eventhistory</querydsl.excludedPackages>
</options>

But I can not figure out how to do this using Gradle.

解决方案

I currently used this build.gradle script to generate QueryDSL types:

project("my-project") {

   sourceSets {
       generated {
           java {
               srcDir 'src/main/generated'
           }
       }
   }

   configurations {
      querydslapt
   }

   dependencies {      
      // your dependencies
      querydslapt  "com.mysema.querydsl:querydsl-apt:3.4.0"
   }

   task generateSources(type: JavaCompile, group: 'build', description: 'Generates the QueryDSL query types') {
       source = sourceSets.main.java
       classpath = configurations.compile + configurations.querydslapt
       options.compilerArgs = ['-proc:only',
                               '-processor',
                               'com.mysema.query.apt.jpa.JPAAnnotationProcessor', 
                               '-Aquerydsl.excludedPackages=com.thomsonreuters.domainmodel.eventhistory']
       options.warnings = false
       destinationDir = file('src/main/generated')
       outputs.dir destinationDir
   }

   compileJava.source generateSources.outputs.files

   clean {
       delete sourceSets.generated.java.srcDirs
   }

}
