导入一个android工程时，出现了以下两条错误：

Caused by: org.gradle.internal.event.ListenerNotificationException: Failed to notify project evaluation listener.


ERROR: Unable to find method 'org.gradle.api.tasks.TaskInputs.property(Ljava/lang/String;Ljava/lang/Object;)Lorg/gradle/api/tasks/TaskInputs;'.
Possible causes for this unexpected error include:
Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
Re-download dependencies and sync project (requires network)

The state of a Gradle build process (daemon) may be corrupt

Cannot load settings from file 'G:\Android\sample\enjoyshop\zhiwen-enjoyshop.iml': File G:\Android\sample\enjoyshop\zhiwen-enjoyshop.iml does not exist Please correct the file content

试了多种方法，现将有效方法记录一下。

首先，查看build.gradle，发现该工程需要依赖greenrobot和bugly的插件，而我的环境中没有安装。

    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.3'
        classpath 'com.novoda:bintray-release:0.8.0' 
        classpath 'org.greenrobot:greendao-gradle-plugin:3.3.0'
        classpath "com.tencent.bugly:tinker-support:1.1.2"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

添加必须的插件后，下边的错误就没有了。

ERROR: Unable to find method ‘org.gradle.api.tasks.TaskInputs.property(Ljava/lang/String;Ljava/lang/Object;)Lorg/gradle/api/tasks/TaskInputs;’
…

插件的添加方法：
1）进入file->settings->plugins，选中marketplace，在搜索栏里输入需要添加的插件名字（如图）。

2）需要的插件筛选出后，点击install，进行安装。
3）安装完成后，点击restart IDE重启AS

查了很多资料，有说插件版本与当前环境不一致导致出现问题的，但又不想一个一个插件查看版本，因此给每一个插件版本指定为latest.release，拉取最新版本。

        classpath 'com.android.tools.build:gradle:3.6.3'
        classpath 'com.novoda:bintray-release:latest.release'
        classpath 'org.greenrobot:greendao-gradle-plugin:latest.release'
        classpath "com.tencent.bugly:tinker-support:latest.release"

然后又出现了新的错误：

0:00	Gradle sync failed: Invalid file found (empty apk data).
		Try to remove G:\Android\sample\enjoyshop\app\build\outputs\apk\debug\output.json or clean your build directory.
		If the error persists, report this issue via Help > Submit Feedback.
		Consult IDE log for more details (Help | Show Log) (1 s 837 ms)

按照提示，我clear了一下工程：Build->（下拉）clear project，然后重新sync一下，终于加载成功了。
