IntelliJ 15 与 QueryDSL 和 Gradle

我在 IntelliJ 15 中有一个使用 gradle 2.3 和 QueryDSL 4.1.3 的 Spring-boot 1.4 项目，该项目无法构建，因为我的实体没有被 Querydsl 构建到 Q 类中。我有以下内容：

 buildscript {
    ext {
        springBootVersion = '1.4.0.BUILD-SNAPSHOT'
        querydslVersion = '4.1.3'
    }
    repositories {
        mavenCentral()
        maven { url "https://repo.spring.io/snapshot" }
        maven { url "https://repo.spring.io/milestone" }
        maven {url "https://plugins.gradle.org/m2/"}
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        classpath "gradle.plugin.com.ewerk.gradle.plugins:querydsl-plugin:1.0.7"
    }
}

apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'eclipse'
apply plugin: 'spring-boot'
apply plugin: 'jacoco'
apply plugin: 'groovy'
apply plugin: "com.ewerk.gradle.plugins.querydsl"

jar {
    baseName = 'billing'
    version = '0.0.1-SNAPSHOT'
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenCentral()
    jcenter()
    maven { url "https://repo.spring.io/snapshot" }
    maven { url "https://repo.spring.io/milestone" }
    maven { url "https://repo.spring.io/libs-snapshot" }
    maven { url "https://repo.spring.io/libs-snapshot"}
    maven {url "https://plugins.gradle.org/m2/"}

}

    }

    testCompile('org.spockframework:spock-spring:1.0-groovy-2.4') {
        exclude group: 'org.spockframework', module: 'spock-core'
    }
    testCompile("junit:junit")

}

sourceSets {
    main {
        output.resourcesDir = output.classesDir
    }
    generated {
        java {
            srcDirs = ['src/main/generated']
        }
    }
}

querydsl {
    library = 'com.mysema.querydsl:querydsl-apt'
    querydslDefault = true
}


test {
    reports.junitXml.destination = file('build/test-results/folder')
}

jacoco {
    toolVersion = "0.7.0.201403182114"
}

jacocoTestReport {
    group = "Reporting"
    description = "Generate Jacoco coverage reports after running tests."
}

configurations {
    querydslapt
}

task wrapper(type: Wrapper) {
    gradleVersion = '2.3'
}

idea {
    module {
        sourceDirs += file('generated/')
        generatedSourceDirs += file('generated/')
    }
}

当我运行单元测试时，出现错误：

Caused by: java.lang.ClassNotFoundException: com.company.billing.customer.QCustomer

当我运行“gradle clean build”时，我得到： 找不到 com.mysema.querydsl:querydsl-apt:。

在以下位置进行了搜索：https://repo1.maven.org/maven2/com/mysema/querydsl/querydsl-apt//querydsl-apt-.pom https://repo1.maven.org/maven2/com/mysema/querydsl/querydsl-apt//querydsl-apt-.pom https://repo1.maven.org/maven2/com/mysema/querydsl/querydsl-apt//querydsl-apt-.jar https://repo1.maven.org/maven2/com/mysema/querydsl/querydsl-apt//querydsl-apt-.jar https://jcenter.bintray.com/com/mysema/querydsl/querydsl-apt//querydsl-apt-.pom https://jcenter.bintray.com/com/mysema/querydsl/querydsl-apt//querydsl-apt-.pom https://jcenter.bintray.com/com/mysema/querydsl/querydsl-apt//querydsl-apt-.jar https://jcenter.bintray.com/com/mysema/querydsl/querydsl-apt//querydsl-apt-.jar https://repo.spring.io/snapshot/com/mysema/querydsl/querydsl-apt//querydsl-apt-.pom https://repo.spring.io/snapshot/com/mysema/querydsl/querydsl-apt//querydsl-apt-.pom https://repo.spring.io/snapshot/com/mysema/querydsl/querydsl-apt//querydsl-apt-.jar https://repo.spring.io/snapshot/com/mysema/querydsl/querydsl-apt//querydsl-apt-.jar https://repo.spring.io/milestone/com/mysema/querydsl/querydsl-apt//querydsl-apt-.pom https://repo.spring.io/milestone/com/mysema/querydsl/querydsl-apt//querydsl-apt-.pom https://repo.spring.io/milestone/com/mysema/querydsl/querydsl-apt//querydsl-apt-.jar https://repo.spring.io/milestone/com/mysema/querydsl/querydsl-apt//querydsl-apt-.jar https://repo.spring.io/libs-snapshot/com/mysema/querydsl/querydsl-apt//querydsl-apt-.pom https://repo.spring.io/libs-snapshot/com/mysema/querydsl/querydsl-apt//querydsl-apt-.pom https://repo.spring.io/libs-snapshot/com/mysema/querydsl/querydsl-apt//querydsl-apt-.jar https://repo.spring.io/libs-snapshot/com/mysema/querydsl/querydsl-apt//querydsl-apt-.jar

我意识到 QueryDsl 在 3 和 4 之间进行了一些包重构，但看起来我的依赖项无法找到，即使它们显然在这里：https://mvnrepository.com/artifact/com.querydsl/querydsl-jpa/4.1.3 https://mvnrepository.com/artifact/com.querydsl/querydsl-jpa/4.1.3

至少，这是我目前关于构建失败原因的理论。有没有人获得最新的 spring、gradle 和 querydsl 来工作？

Update: 我删除了 ewerk 插件并简化了我的 build.gradle 文件，因此现在一切都可以正常构建。我正在更新以帮助其他可能需要此信息的人：

您是否看到 Gradle 输出中生成了 QClass？从您的错误来看，它似乎已经超过了应该生成它们的点。

我认为问题是你没有配置JPAAnnotationProcessor。这是为了方便在 gradle 中通过将 :jpa 附加到您的 querydsl-apt 依赖项来完成的。在 Maven 中，您应用插件manually http://www.baeldung.com/rest-api-search-language-spring-data-querydsl.

我的 build.gradle 中有以下与 querydsl 相关的内容。

idea {
    module {
        sourceDirs += file('generated/')
        generatedSourceDirs += file('generated/')
    }
}
[...]
compile "com.querydsl:querydsl-root:$querydslVersion"
compile "com.querydsl:querydsl-jpa:$querydslVersion"
compile "com.querydsl:querydsl-apt:$querydslVersion:jpa

idea 块只是自动配置 IDEA 中生成的源目录，以便 IDE 中的构建正常工作。

EDIT:

The JPAAnnotationProcessor输出如下所示。

Note: Running JPAAnnotationProcessor
Note: Serializing Supertypes
Note: Generating com.myclass.example.QMappedSuperClass for [com.myclass.example.MappedSuperClass]
Note: Serializing Entity types
Note: Generating com.myclass.example.QMyClass for [com.myclass.example.MyClass]

EDIT:

我对 ewerk 插件不熟悉，所以我看了看。它似乎正在尝试为您激活 JPAAnnotationProcessor。您可能需要根据文档设置 JPA 标志here https://github.com/ewerk/gradle-plugins/tree/master/querydsl-plugin因为它默认为 false。

请参阅有关依赖性问题的评论线程。 编辑：对于摇篮 4.6+ https://docs.gradle.org/4.6/release-notes.html#convenient-declaration-of-annotation-processor-dependencies，您可以使用annotationProcessor syntax.

api "com.querydsl:querydsl-root:$querydslVersion"
api "com.querydsl:querydsl-jpa:$querydslVersion"
annotationProcessor "com.querydsl:querydsl-apt:$querydslVersion:jpa"
