gradle - Gradle解决多项目依赖项中的ext属性

Question

我具有以下多项目结构(仅显示重要部分):

- project
    - build.gradle (file) 
    - settings.gradle (file)
    + module1 (dir)
    + module2 (dir)

build.gradle:

ext {
    groovyMajorVersion = 2.4
    groovyMinorVersion = 3
}
subprojects {
    dependencies {
        testCompile 'org.codehaus.groovy:groovy-all:${groovyMajorVersion}.${groovyMinorVersion}'
        testCompile 'org.spockframework:spock-core:1.0-groovy-${groovyMajorVersion}'
    }
}

settings.gradle:

include 'module1', 'module2'

当我从module1运行 gradle dependencies时，出现以下错误:

testCompile - Compile classpath for source set 'test'.
+--- org.codehaus.groovy:groovy-all:${groovyMajorVersion}.${groovyMinorVersion} FAILED
\--- org.spockframework:spock-core:1.0-groovy-${groovyMajorVersion} FAILED

Answer 1

这是因为在依赖关系块中，您用撇号(')而不是反向逗号(")包装依赖关系，因此依赖关系内部的参数无法解析。要解决此问题，只需将引号替换为反逗号，即:

    testCompile "org.codehaus.groovy:groovy-all:${groovyMajorVersion}.${groovyMinorVersion}"
    testCompile "org.spockframework:spock-core:1.0-groovy-${groovyMajorVersion}"
