gradle学习(18)-ant的属性

1.设置ant属性

build.xml:

<project>
<target name="hello">
        <echo>buildDir=${buildDir}</echo>
 </target>
</project>

我们要给buildDir属性设值

ant.importBuild ("build.xml"){
        antTargetName ->"a-"+antTargetName
}
task intro << {
        println "Hello,from gradle"
}
ant.buildDir = buildDir
ant.properties.buildDir = buildDir
ant.properties["buildDir"] = buildDir
ant.property(name:"buildDir",location:buildDir)

2.获取ant属性值

build.xml中定义属性：

<project>
<property name="antProp" value="a property defined in an Ant build"/>
<target name="hello">
        <echo>buildDir=${buildDir}</echo>
 </target>
</project>

gradle.xml获取属性

ant.importBuild ("build.xml"){
        antTargetName ->"a-"+antTargetName
}
task intro << {
        println "Hello,from gradle"
}
ant.buildDir = buildDir
ant.properties.buildDir = buildDir
ant.properties["buildDir"] = buildDir
ant.property(name:"buildDir",location:buildDir)
println ant.antProp

执行gradle命令，输出如下：

qianhuis-Mac-mini:0112 qianhui$ gradle intro
a property defined in an Ant build
:intro
Hello,from gradle

3.设置reference的值

build.xml

<project>
<property name="antProp" value="a property defined in an Ant build"/>
<path refid="classpath"/>
<target name="hello">
        <echo>buildDir=${buildDir}</echo>
 </target>
</project>

最后三行是设置代码

ant.importBuild ("build.xml"){
        antTargetName ->"a-"+antTargetName
}
task intro << {
        println "Hello,from gradle"
}
ant.buildDir = buildDir
ant.properties.buildDir = buildDir
ant.properties["buildDir"] = buildDir
ant.property(name:"buildDir",location:buildDir)
println ant.antProp
ant.path(id:"classpath",location:"libs")
ant.references.classpath = ant.path(location:"libs")
ant.references["classpath"] = ant.path(location:"libs")

4.获取reference的值

build.xml

<project>
<property name="antProp" value="a property defined in an Ant build"/>
<path refid="classpath"/>
<path id="antPath" location="libs"/>
<target name="hello">
        <echo>buildDir=${buildDir}</echo>
 </target>
</project>

build.gradle

ant.importBuild ("build.xml"){
        antTargetName ->"a-"+antTargetName
}
task intro << {
        println "Hello,from gradle"
}
ant.buildDir = buildDir
ant.properties.buildDir = buildDir
ant.properties["buildDir"] = buildDir
ant.property(name:"buildDir",location:buildDir)
println ant.antProp
ant.path(id:"classpath",location:"libs")
ant.references.classpath = ant.path(location:"libs")
ant.references["classpath"] = ant.path(location:"libs")

println ant.references.antPath
println ant.references["antPath"]

输出如下：

qianhuis-Mac-mini:0112 qianhui$ gradle intro
a property defined in an Ant build
/Users/qianhui/Documents/Developer/gradle_project/0112/libs
/Users/qianhui/Documents/Developer/gradle_project/0112/libs
:intro
Hello,from gradle
