Android Studio 不会导出 Jar

Question

>我创建一个新的安卓工作室项目，添加新模块

我通过这条路径获得 Unity 插件 "D：\Unity\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\mono\Release\Classes">

我将类.jar添加到我的图书馆>库 右键单击"类.jar"并添加库

编辑我的图书馆>构建.gradle，像这样

apply plugin: 'com.android.library'
android {
compileSdkVersion 28
defaultConfig {
minSdkVersion 15
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:28.0.0-rc02'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation files('libs/classes.jar')
}
task deleteOldJar(type: Delete) {
delete 'release/AndroidPlugin.jar'
}
task exportJar(type: Copy) {
from('build/intermediates/bundles/release/')
into('release/')
include('classes.jar')
rename('classes.jar', 'AndroidPlugin.jar')
}
exportJar.dependsOn(deleteOldJar, build)

并添加 Java

package com.example.mylibrary;
import android.app.AlertDialog;
import com.unity3d.player.UnityPlayer;
import com.unity3d.player.UnityPlayerActivity;
public class GetUrl extends UnityPlayerActivity {
public static void Show(final String title, final String content)
{
UnityPlayer.currentActivity.runOnUiThread(new Runnable() {
public void run() {
AlertDialog.Builder builder = new AlertDialog.Builder(UnityPlayer.currentActivity);
builder.setTitle(title).setMessage(content).setCancelable(false).setPositiveButton("OK", null);
builder.show();
}
});
}
}

刷新后，我打开grable菜单，双击createJar，但没有任何文件生成

我正在寻找很多教程并遵循，尝试几个小时，几乎相同的步骤，但仍然没有结果，您有什么想法吗？ D：

删除代码：

task deleteOldJar(type: Delete) {
delete 'release/AndroidPlugin.jar'
}
task exportJar(type: Copy) {
from('build/intermediates/bundles/release/')
into('release/')
include('classes.jar')
rename('classes.jar', 'AndroidPlugin.jar')
}
exportJar.dependsOn(deleteOldJar, build)

只需双击 mylibrary gradle 操作下的构建函数即可。然后从/YourAndroidProject/mylibrary/build/outputs/aar/mylibrary-debug.aar获取新生成的mylibrary-debug.aar文件，并将其拖到unity项目中的Plugins/Android文件夹中。
