我的Java项目的gradle构建错误

Question

I am trying to build the Java project located at here: https://github.com/garlicPasta/dotServer

I'm new to Gradle. I downloaded the latest Gradle now (v4.0). I added the bin folder of Gradle (which includes gradle.bat ) to the path so I can run gradle command everywhere. Looks like the project requires Google protobuf which it downloads automatically. But when I start the command gradle build , I get the following error:

> Configure project :
You are using Gradle 4.0:  This version of the protobuf plugin works with Gradle version 2.12+


FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'dotServer'.
> No signature of method: org.gradle.api.internal.tasks.DefaultTaskInputs.source() is applicable for argument types: (com.google.protobuf.gradle.ProtobufSourceDirectorySet_Decorated) values: [main Proto source]
  Possible solutions: collect(), use([Ljava.lang.Object;)

Where is the problem coming from? Can someone try to build the project and let me know?

Answer 1

I just upgraded to Android Studio 3 and had the same problem when I upgrade Gradle and it's plugin.

We use Google's Protobuf which was included in build.gradle with version 0.7.6. I just changed to 0.8.3 and it builds now.

buildscript {
...
dependencies {
        classpath 'com.google.protobuf:protobuf-gradle-plugin:0.8.3'
    }
}
