判断是否 AGP7+ 的方法

如何判断？

    /**
     * 是否是AGP7.0.0及以上
     * @param project
     * @return
     */
    static boolean isAGP7_0_0(Project project) {
        def androidComponents = project.extensions.findByName("androidComponents")
        if (androidComponents && androidComponents.hasProperty("pluginVersion")) {
            return true
        }
        return false
    }


    /**
     * 是否是AGP7.4.0及以上
     * @param project
     * @return
     */
    static boolean isAGP7_4_0(Project project) {
        def androidComponents = project.extensions.findByName("androidComponents")
        if (androidComponents && androidComponents.hasProperty("pluginVersion") && (androidComponents.pluginVersion.major > 7 || androidComponents.pluginVersion.minor >= 4)) {
            return true
        }
        return false
    }

测试

def androidComponents = target.extensions.findByName("androidComponents")
for (String key : androidComponents.properties.keySet()) {
    println("androidComponents k =" + key + "  val =" + androidComponents.properties.get(key))
    printF(androidComponents.properties.get(key))
    if (key === "pluginVersion") {
        println("major version: " + androidComponents.pluginVersion.major)
        println("minor version: " + androidComponents.pluginVersion.minor)
    }
}

我如何知道 androidComponents.pluginVersion 有 major 和 minor 字段？

打印一个类的所有属性

void printF(Object obj) {
    def clazz = obj.getClass()
    def fields = clazz.getDeclaredFields()
    String s = "default"
    for (Field f : fields) {
        def modifiers = f.getModifiers();
        if (Modifier.isPublic(modifiers)) {
            s = "public"
        } else if (Modifier.isPrivate(modifiers)) {
            s = "private"
        } else if (Modifier.isProtected(modifiers)) {
            s = "protected"
        }
        f.setAccessible(true)
        println("\t\tfield = " + s + "\t" + f.getType().getSimpleName() + "\t" + f.getName())
    }
    println("")
    println("")
}
