类似问题：Android studio gradle 卡在 Fastutil.7.2.0.jar
当我用 Java 构建我的第一个 Android 应用程序时，Android Studio 4.0 总是抱怨：
Could not GET 'https://jcenter.bintray.com/it/unimi/dsi/fastutil/7.2.0/fastutil-7.2.0.jar'. Received status code 400 from server: Bad Request
Enable Gradle 'offline mode' and sync project
但是，可以jar使用浏览器下载。
如果我删除jcenter()in build.gradle，则会发生类似的错误：
Could not HEAD 'https://dl.google.com/dl/android/maven2/org/jetbrains/kotlin/kotlin-stdlib-jdk8/1.3.72/kotlin-stdlib-jdk8-1.3.72.pom'. Received status code 400 from server: Bad Request
Enable Gradle 'offline mode' and sync project
这个文件甚至不存在。
我尝试修改build.gradle或设置代理，但都不起作用。
gradle.build文件：
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:4.0.0"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
更新：
解决了。代理的错。检查C:\Users\USERNAME\.gradle\gradle.properties。
