Question

我在我的gradle项目中使用lombok并且想要创建一个jar文件，但每次执行jar任务时（无论是否在我的控制台或eclipse ide中触发）我都会得到错误，我的lombok导入无法在这些类中找到我在哪里使用lombok注释。示例输出：

... other lombok related error messages ...

* What went wrong:
Execution failed for task ':compileJpaModelgen'.
> Compilation failed; see the compiler error output for details.

* Try:

经过一段时间的搜索，我发现有一个gradle和lombok的插件，但是对于使用较新的gradle版本进行编译并不是真的需要。我的gradle版本是3.4.1和lombok 1.6.18。

在another thread我发现可能是一个类似的错误，但是有了maven。我想在我的build.gradle中尝试这个，但我不知道如何编写/定义这个......

使用我的Eclipse ide启动和运行我的Spring启动应用程序工作正常;只有gradle compileJava任务在编译时似乎与lombok有问题。

这是我的build.gradle：

buildscript {
    repositories { 
        mavenCentral()
        jcenter()
    }
    dependencies { classpath("org.springframework.boot:spring-boot-gradle-plugin:+") }
}

plugins { 
    id 'at.comm_unity.gradle.plugins.jpamodelgen' version '1.1.3'
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'at.comm_unity.gradle.plugins.jpamodelgen'
apply plugin: 'war'

war {
    baseName = 'test'
    version =  '0.0.1'
}

repositories { mavenCentral() }

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {

    compile "org.springframework.boot:spring-boot-starter-data-jpa"
    compile "org.springframework.boot:spring-boot-starter-data-rest"
    compile("org.springframework.boot:spring-boot-devtools")

    compile group: 'org.apache.commons', name: 'commons-lang3', version: '3.5'
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

sourceSets {
    generated { java.srcDir "${buildDir}/generated/src/java/" }
}

ext['hibernate.version'] = '5.2.10.Final'


jpaModelgen {
    library = "org.hibernate:hibernate-jpamodelgen:5.2.10.Final"
    jpaModelgenSourcesDir = "src/generated/java"
}

compileJava.options.compilerArgs += ["-proc:none"]

Answer 1

compileJava.options.compilerArgs + = [ “ -proc：only”， ]

Gradle，Lombok＆amp; JPAMetalModel处理器：Project不编译（包lombok不存在）
