Gradle 渐变：从另一个子项目设置子项目属性

设置。渐变

include ':projectA',':projectB'

task task1()  {
    doFirst {
        println 'setting project.ext.testProperty1'
        project(':projectB').ext.testProperty1 = 'MyProperty'
    }
}

task task2 (dependsOn: ['task1', ':projectB:task3']) {
    doLast {
        println "Executed project B Task3 from projectA task2"
    }
}

task task3() {
    doLast {
        println "task3 from projectB"
        println project(':projectB').ext.testProperty1
        if(project(':projectB').ext.hasProperty("testProperty1")) {
            ext.prop1  = project.property("testProperty1")
            println "+++++++++If : Clause++++++++++++++++++++++++++++++++"
        } else {
            println "+++++++++Else  :Clause++++++++++++++++++++++++++++++++"
        }
    }
}

projectA/build.gradle

include ':projectA',':projectB'

task task1()  {
    doFirst {
        println 'setting project.ext.testProperty1'
        project(':projectB').ext.testProperty1 = 'MyProperty'
    }
}

task task2 (dependsOn: ['task1', ':projectB:task3']) {
    doLast {
        println "Executed project B Task3 from projectA task2"
    }
}

task task3() {
    doLast {
        println "task3 from projectB"
        println project(':projectB').ext.testProperty1
        if(project(':projectB').ext.hasProperty("testProperty1")) {
            ext.prop1  = project.property("testProperty1")
            println "+++++++++If : Clause++++++++++++++++++++++++++++++++"
        } else {
            println "+++++++++Else  :Clause++++++++++++++++++++++++++++++++"
        }
    }
}

projectB/build.gradle

include ':projectA',':projectB'

task task1()  {
    doFirst {
        println 'setting project.ext.testProperty1'
        project(':projectB').ext.testProperty1 = 'MyProperty'
    }
}

task task2 (dependsOn: ['task1', ':projectB:task3']) {
    doLast {
        println "Executed project B Task3 from projectA task2"
    }
}

task task3() {
    doLast {
        println "task3 from projectB"
        println project(':projectB').ext.testProperty1
        if(project(':projectB').ext.hasProperty("testProperty1")) {
            ext.prop1  = project.property("testProperty1")
            println "+++++++++If : Clause++++++++++++++++++++++++++++++++"
        } else {
            println "+++++++++Else  :Clause++++++++++++++++++++++++++++++++"
        }
    }
}

现在，当我调用gradle task2时，我得到的输出总是

$ ../gradlew task2
:projectA:task1
setting project.ext.testProperty1
:projectB:task3
task3 from projectB
MyProperty
+++++++++Else  :Clause++++++++++++++++++++++++++++++++
:projectA:task2
Executed project B Task3 from projectA task2

它从未进入“If”子句，我遗漏了什么，它甚至似乎在ProjectB中获得ext.property testProperty1，但hasProperties似乎没有正确计算它

如果从代码中去掉“ext”

if(project(':projectB').ext.hasProperty("testProperty1")) 

改成

if(project(':projectB').hasProperty("testProperty1")) 

然后是if子句，我不知道为什么在readtime使用ext会引起问题，而我们可以在writetime使用它
