java - 找不到MoreTypes类

Question

我有一个使用dagger-2和grpc的Java项目，当我尝试使用./gradlew build进行构建时，出现以下错误:

> java.lang.NoClassDefFoundError: com/google/auto/common/MoreTypes

应该在Dagger-2依赖项中提供MoreTypes还是在类路径上提供该依赖项？

这是gradle.build文件内容的相关部分:

plugins {
    id "net.ltgt.apt" version "0.10"
    id "com.google.protobuf" version "0.8.1"
    id "java"
}

dependencies {
    compile 'io.grpc:grpc-all:1.5.0'

    compile 'com.google.dagger:dagger:2.14'
    apt 'com.google.dagger:dagger-compiler:2.14'

    testApt 'com.google.dagger:dagger-compiler:2.14'

   }



apply plugin: 'java'

sourceCompatibility = 1.8
targetCompatibility = 1.8

Answer 1

这是2.14.1中修复的Dagger 2.14中的问题。参见issue 994，“ Dagger 2.14中断构建”:

I have not isolated the issue to a small sample project at this point, but a possible cause I see is below, maybe that gives a pointer. I don't have any explicit dependency on Google Auto libs in that part of the build.

java.lang.NoClassDefFoundError: com/google/auto/common/MoreTypes

确认已在2.14.1中修复，其中包含 this commit。
