引入Google protobuf的时候报上述错误

group ‘com.jiangdashuai‘
version ‘1.0‘

apply plugin: ‘java‘

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
//    testCompile group: ‘junit‘, name: ‘junit‘, version: ‘4.12‘
    compile(
             ‘io.netty:netty-all:4.1.19.Final‘,
            ‘com.google.protobuf:protobuf-java:3.5.1‘,
            ‘com.google.protobuf:protobuf-lite:3.0.1‘
    )
}

将引入的插件

apply plugin: ‘java‘

改为

apply plugin: ‘java‘
apply plugin: ‘idea‘
