TWA应用程序错误：java。lang.NoClassDefFoundError

Question

我正在把我的pwa网站改成twa，我遇到了一些麻烦。

当我尝试同步或构建项目时，我遇到以下错误：

失败：生成失败，出现异常。

• 出了什么问题：java。lang.NoClassDefFoundError：

JAVAlang.NoClassDefFoundError（无错误消息）

我不熟悉android和java，有人能帮我吗？

我正在使用bubblewrap/cli我的gradle：

preBuild.dependsOn(generateShorcutsFile)

repositories {

dependencies {

}

编辑：我在任何项目中都遇到了相同的错误，即使是android Studio中的bult。已经重新安装了android Studio、XAMPP、java和node。

对于无法解析符号MarkupBuilder：将groovy类路径添加到构建中。如果使用的是gradle 7

buildscript {
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:7.0.0'
        classpath 'org.codehaus.groovy:groovy-xml:3.0.8'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
        google()
        mavenCentral()
    }
}
task clean(type: Delete) {
    delete rootProject.buildDir
}
