Java android studio中我的应用程序生成异常

我的应用程序运行正常，但现在我收到以下生成失败消息：

无法加载类“com.jcraft.jsch.JSchException”

我试图下载jsch-0.1.55 jar文件并将其插入到libs文件中，但没有成功。我还尝试卸载Android studio，然后重新安装。

并尝试将其添加到app/build.gridle文件：

实现文件树（目录：“libs”，包括：['jsch-0.1.55.jar']）

我也试过：

实现文件（'libs/jsch-0.1.55.jar'）

这是：

实现'com.jcraft:jsch:0.1.55'

并确保将maven url添加到project/build.gradle文件中

allprojects {
    repositories {
        google()
        maven { url 'https://maven.google.com' }
        jcenter()
    }
}

这是我的堆栈跟踪：

像这样在gradle中使用Maven而不是使用JAR文件编译JSch

在app\build.gradle中添加依赖项

dependencies {
    compile 'com.jcraft:jsch:0.1.54'
}

在project\build.gradle中添加maven（如果您以前没有添加它）

allprojects {
    repositories {
        jcenter()
        maven { url 'https://maven.google.com' }
        google()
    }

决心！ 我不确定到底发生了什么，但我使用了这个版本的jcraft libs/jsch-0.1.55.jar 已解决！ 我不确定到底发生了什么，但我使用了这个版本的jcraft libs/jsch-0.1.55.jar

为什么要下载JAR而不是简单地添加jsch：我也这么做了，但它不起作用，即使将它添加到build.gradle文件的依赖项中，它也无法同步，因为它无法加载类“com.jcraft.jsch.JSchException”。为什么要下载JAR而不是简单地添加jsch：我也这么做了，但它不起作用，即使将其添加到build.gradle文件的依赖项中，它也无法同步，因为它无法加载类“com.jcraft.jsch.JSchException”。我刚刚加载了类“com.jcraft.jsch.JSchException”，但仍然得到以下结果：无法加载类“com.jcraft.jsch.JSchException”
