“gradle init”（v4.0）生成build.gradle找不到包

Question

我使用“gradle init”将工作的Maven项目转换为Gradle。我收到的包不存在错误。我不知道如何调试这个错误。

$ ./gradlew build 
Starting a Gradle Daemon (subsequent builds will be faster)

钻/逻辑目录的build.gradle：

$ cat build.gradle 

description = 'Logical Plan, Base expressions' 
dependencies { 
    compile project(':drill-protocol') 
    compile project(':drill-common') 
    compile(group: 'org.apache.calcite', name: 'calcite-core', version:'1.4.0-drill-r21') { 
     exclude(module: 'jgrapht-jdk1.5') 
     exclude(module: 'commons-logging') 
     exclude(module: 'jackson-annotations') 
     exclude(module: 'jackson-core') 
     exclude(module: 'jackson-databind') 
    } 

    compile group: 'com.typesafe', name: 'config', version:'1.0.0' 
    compile group: 'org.apache.commons', name: 'commons-lang3', version:'3.1' 
    compile group: 'org.msgpack', name: 'msgpack', version:'0.6.6' 
    compile group: 'org.reflections', name: 'reflections', version:'0.9.8' 
    compile group: 'com.fasterxml.jackson.core', name: 'jackson-annotations', version:'2.7.1' 
    compile group: 'com.fasterxml.jackson.core', name: 'jackson-databind', version:'2.7.1' 
    compile group: 'com.codahale.metrics', name: 'metrics-core', version:'3.0.1' 
    compile group: 'com.codahale.metrics', name: 'metrics-servlets', version:'3.0.1' 
    compile group: 'org.antlr', name: 'antlr-runtime', version:'3.4' 
    compile group: 'joda-time', name: 'joda-time', version:'2.9' 

    testCompile project(':drill-common') 
} 

task packageTests(type: Jar) { 
    from sourceSets.test.output 
    classifier = 'tests' 
} 

我是不是看错了的build.gradle文件？最上面的build.gradle列出了与它的pom.xml一对一匹配的依赖和存储库。

我该找什么？

Answer 1

您缺少的类是由ANTLR生成的。您的回购库中有一个ANTLR语法文件，从中可以生成这些文件。像Maven构建中使用的大多数插件一样，这不会自动传输到Gradle，而必须手动完成。使用内置的Gradle ANTLR插件从语法文件生成源代码。
