Question

我习惯配置gradle构建以在build.gradle中使用jQAssistent（基本上）这个片段：

    project.ext["jqaversion"] = "1.3.0"
    project.ext["jqacoreversion"] = "1.3"
    configurations {
        jqaRuntime
    }

    dependencies {
        // jQA 1.2
    //    jqaRuntime("com.buschmais.jqassistant:commandline:${project.jqaversion}")
        // jQA 1.3
        jqaRuntime("com.buschmais.jqassistant:jqassistant-commandline:${project.jqaversion}")

        jqaRuntime("com.buschmais.jqassistant.plugin:java:${project.jqacoreversion}")
        jqaRuntime("com.buschmais.jqassistant.plugin:junit:${project.jqacoreversion}")
    }

    task removeJQAReport(type: Delete) {
        delete 'jqassistant/report'
        delete 'jqassistant/store'
    }

    task(jqascan, dependsOn: 'removeJQAReport', type: JavaExec) {
        main = 'com.buschmais.jqassistant.commandline.Main'
        classpath = configurations.jqaRuntime
        args 'scan'
        args '-p'
        args 'jqassistant/jqassistant.properties'
        args '-f'
        args 'java:classpath::build/classes/main'
        args 'java:classpath::build/classes/test'
    }

    task(jqaanalyze, type: JavaExec) {
        main = 'com.buschmais.jqassistant.commandline.Main'
        classpath = configurations.jqaRuntime
        args 'analyze'
        args '-r'
        args 'jqassistant/jqassistant-rules'
    }

    task(jqa, dependsOn: ['jqascan', 'jqaanalyze']) {
        jqaanalyze.mustRunAfter jqascan
    }

    task(jqs, type: JavaExec) {
        main = 'com.buschmais.jqassistant.commandline.Main'
        classpath = configurations.jqaRuntime
        args 'server'
        standardInput = System.in
    }

直到jQA 1.2.0才能正常工作。更新到1.3.0后，我遇到了这个例外：

找到完整的示例

Maven项目工作正常，命令行jQA版本无法下载1.3（只有1.2）。

有什么想法吗？我是否必须为1.3？

明确指定Neo4j版本

Answer 1

显然，这是一个Gradle类路径问题，因为jQAssistant命令行分配工作正常。所以我通过以下方式修改了build.gradle文件：

    dependencies {
        jqaRuntime("com.buschmais.jqassistant:jqassistant-commandline:${project.jqaversion}") {
            // because jQA 1.3 comes with Neo4j 2 and 3 support, there would be a classpath conflict
            exclude module: 'neo4j'
        }

        jqaRuntime("com.buschmais.jqassistant.plugin:java:${project.jqaversion.substring(0, 3)}")
        jqaRuntime("com.buschmais.jqassistant.plugin:junit:${project.jqaversion.substring(0, 3)}")
    }

https://github.com/kontext-e/jqa-gradle中提到的示例也以这种方式更新。

切换到1.3.0后，jQAssistant命令行停止工作
