annotationProcessors 多模块项目 Java
annotationProcessors multi module project Java
我最近开始学习 java 处理器并尝试将它们与 gradle 一起使用,
当我构建项目时,我可以看到打印了注释处理器 jars(其他模块)(我在 app gradle 文件中添加了它,您可以在下面看到),但没有执行。
我不知道我做错了什么...
我有一个具有以下结构的多模块项目
ROOT
|
|-app # contains main classes
|-annotations
|-processors
处理器项目gradle文件:
plugins {
id 'java'
}
group 'org.example'
version '1.0-beta'
repositories {
mavenCentral()
}
dependencies {
compileOnly project(":annotations")
implementation(project(":annotations"))
testImplementation 'org.junit.jupiter:junit-jupiter-api:5.7.0'
testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.7.0'
}
test {
useJUnitPlatform()
}
应用程序gradle文件
plugins {
id 'java'
}
group 'org.example'
version '1.0-SNAPSHOT'
repositories {
mavenCentral()
}
tasks.withType(JavaCompile) {
doFirst {
println "AnnotationProcessorPath for $name is ${options.getAnnotationProcessorPath().getFiles()}"
}
}
compileJava {
options.annotationProcessorPath = configurations.annotationProcessor
}
dependencies {
compileOnly project(":annotations")
implementation project(":annotations")
implementation project(":processors")
annotationProcessor project(":processors")
// annotationProcessor "org.example:processors:1.0-beta"
testImplementation 'org.junit.jupiter:junit-jupiter-api:5.7.0'
testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.7.0'
}
test {
useJUnitPlatform()
}
注解一个为默认一个
我有一个记录和创建文件的处理器
@Override
public boolean process(Set<? extends TypeElement> set, RoundEnvironment roundEnvironment) {
processingEnv.getMessager().printMessage(Diagnostic.Kind.ERROR,"Testa asdfasdf");
...
在我的应用程序模块中,我有一个 class 注释模块中声明的 @Builder 注释,因此处理器应该被执行
应用gradle文件的输出

几个小时后,它通过在处理器模块
下创建文件javax.annotation.processing.Processor来工作
ROOT
|
--app # contains main classes
--annotations
--processors
|--main
|--java
|--resources
|--META-INF
|--services
|--javax.annotation.processing.Processor
|--test
将其内容设置为处理器路径,在我的例子中
com.example.processors.BuilderProcessor
