votes

I have attempted to rebuild the jar for https://github.com/square/okhttp library. However, this is the error I get after first cloning it and then calling "gradle assemble". Is there something incorrect about my method?

FAILURE: Build failed with an exception.

  • Where: Build file '/Users/test/okhttptest/okhttp/build.gradle' line: 75

  • What went wrong: Plugin [id: 'ru.vyarus.animalsniffer', version: '1.5.1'] was not found in any of the following sources:

  • Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
  • Plugin Repositories (could not resolve plugin artifact 'ru.vyarus.animalsniffer:ru.vyarus.animalsniffer.gradle.plugin:1.5.1') Searched in the following repositories: Gradle Central Plugin Repository

  • Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

  • Get more help at https://help.gradle.org

BUILD FAILED in 617ms

You problem is that you are using a locally installed gradle version since your call is "gradle assemble". your gradle version is propably too old so you it can't handle the plugin.

This repository has a gradle-wrapper (gradlew) checked in.

https://docs.gradle.org/current/userguide/gradle_wrapper.html

change your call into ./gradlew assemble and the wrapper will handle the download of the required gradle version and will handle all the dependencies for you.
