Question

我想在Gradle Script中访问StringUtils方法。因此我在buildscript闭包中定义了它的MavenRepo。在我添加了import语句后，我以为我能够使用这个类。但错误告诉我不然。我错过了什么？

gradle.build

import org.apache.commons.lang.StringUtils

apply plugin: "java"
apply plugin: "application"

mainClassName = "com.xetra11.test.Main"

task execute(){
     File file = new File("/log/file.txt")
     StringUtils.touch("/log/file.txt")
}

buildscript {
    repositories{
        mavenCentral()
    }
    dependencies {
        classpath group: 'org.apache.commons', name: 'commons-lang3', version: '3.0'
    }
}

repositories{
    mavenCentral()
 }

dependencies{
    compile group: 'org.apache.commons', name: 'commons-lang3', version: '3.0'
}

错误输出

~/Workspace/Development/Java/gradle_test/ gradle buildDependents

org.apache.commons.lang.StringUtils，从它的包中暗示，是在公共场所2.x. commons-lang3的软件包名称已更改为org.apache.commons.lang3。

因此，要么使用org.apache.commons:commons-lang:2.6作为依赖关系，要么将导入更改为org.apache.commons.lang3.StringUtils
