AndroidStudio 更新后，Gradle 项目刷新失败

Question

I built some android projects with android studio 1.4. Today my computer broke and I reinstalled my operating system . I installed android studio 1.5,but it didn't work with the old projects.I built some new projects and there's no errors.When I open the old projects,there is an error.

Error:Unable to tunnel through proxy. Proxy returns "HTTP/1.1 400 Bad Request"

I can't find any information about this error,how can I deal with the old projects? enter image description here

Answer 1

Put this code in your main build.gridle file, may be it trying to use latest gradle and you have used older one in your previous projects.

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0'

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

allprojects {
    repositories {
        jcenter()
    }
}

这个问题解决了.gradle.org/distributions/gradle-2.8-all.zip.它对我有用。

Answer 3

I have a network restriction at my production environment that causes this issue.

I solved the same problem by downloading a Gradle version manually and use this local deployment directly:

1. Downloading a proper Gradle version from Gradle site. In my case https://services.gradle.org/distributions/gradle-6.4.1-all.zip
2. Placing this zip file in a proper disk folder, say /path/to/gradle-6.4.1-all.zip
3. Editing projRoot > gradle > wrapper > gradle-wrapper.properties , so that

distributionUrl=file:///path/to/gradle-6.4.1-all.zip

A robust and cross-platform setup would be

distributionUrl=gradle-6.4.1-all.zip

This is a relative path to

project_root/android/gradle/wrapper/

So you must copy the Gradle zip ball there.
