Gradle插件混淆/与AutoValue和FreeBuilder的冲突

Question

我正在试验Gradle/IntelliJ和各种Java构建器/容器。但是，我无法在同一个项目中同时配置org.inferred.FreeBuilder和com.google.auto.value.AutoValue。

使用下面的build.gradle文件，我能够成功地编译一个用AutoValue命名的类(来自AutoValue 文档的动物示例)。

但是，一旦我取消注释"id 'org.inferred.processors“和"processor‘org.Inference.FreeBuilder:1.14.6’”，我就会得到

:processorPath \main\java\example\com\Animal.java:12: error:无法找到符号返回新的AutoValue_Animal (名称，numberOfLegs)；^符号:类AutoValue_Animal位置: class AutoValue_Animal 1错误:编译AutoValue_Animal失败

plugins {
    id 'java'
    id 'idea'
    id 'net.ltgt.apt-idea'  version '0.13'
    // id 'org.inferred.processors' version '1.2.15'
}

version '1.0-SNAPSHOT'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    compile 'com.google.auto.value:auto-value:1.5.1'
    apt 'com.google.auto.value:auto-value:1.5.1'

    //processor 'org.inferred:freebuilder:1.14.6'
}

jar {
    from {
        (configurations.runtime).collect {
            it.isDirectory() ? it : zipTree(it)
        }
    }
    manifest {
        attributes 'Main-Class': 'example.com.Main'
    }
}

idea {
    project {
        // experimental: whether annotation processing will be configured in the IDE; only actually used with the 'idea' task.
        configureAnnotationProcessing = true
    }
    module {
        apt {
            // whether generated sources dirs are added as generated sources root
            addGeneratedSourcesDirs = true
            // whether the apt and testApt dependencies are added as module dependencies
            addAptDependencies = true

            // The following are mostly internal details; you shouldn't ever need to configure them.
            // whether the compileOnly and testCompileOnly dependencies are added as module dependencies
            addCompileOnlyDependencies = false // defaults to true in Gradle < 2.12
            // the dependency scope used for apt and/or compileOnly dependencies (when enabled above)
            mainDependenciesScope = "PROVIDED" // defaults to "COMPILE" in Gradle < 3.4, or when using the Gradle integration in IntelliJ IDEA
        }
    }
}

我正试图从这些消息来源中提取信息：

• https://github.com/google/auto/issues/106#issuecomment-299005192
• https://github.com/google/auto/blob/master/value/userguide/index.md#in-your-value-class
• 无法用AutoValue和IntelliJ解析符号

Answer 1

您可以在项目中使用两个gradle依赖项，但不能同时使用它们的gradle插件。你也不需要。

您只需要一个gradle插件来支持注释处理器(它们中的任何一个)，那么所有bean处理器依赖项都应该可以工作。
