java - Gradle 找不到 guava-*version*-cdi1.0.jar

Question

可能是显而易见的事情，但这个问题让我卡住了一段时间。

一些库需要 com.google.guava:guava:21.0 作为依赖项，但是 gradle 无法从 maven 存储库中获取它。这是一个遗留项目，所以版本不是最新的。

错误日志:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileJava'.
> Could not resolve all files for configuration ':compileClasspath'.
   > Could not find guava-21.0-cdi1.0.jar (com.google.guava:guava:21.0).
     Searched in the following locations:
         https://repo.maven.apache.org/maven2/com/google/guava/guava/21.0/guava-21.0-cdi1.0.jar

guava-21.0.jar(无 -cdi1.0 后缀)存在于该路径上。为什么 gradle 向文件名添加 -cdi1.0 后缀，是否可以禁用此功能？或者我只是误解了一些东西，还有其他东西在起作用？

我试图单独指定 guava dep compile(group: 'com.google.guava', name: 'guava', version: '21.0')，但是它不会影响任何东西。

build.gradle:(由 gradle init 从 maven pom.xml 生成)

plugins {
    id 'java'
    id 'maven-publish'
}

repositories {
    mavenCentral()
    maven {
        url = 'http://repo.maven.apache.org/maven2'
    }
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web:1.4.1.RELEASE'
    implementation 'org.springframework.boot:spring-boot-starter-jdbc:1.4.1.RELEASE'
    implementation 'org.springframework.boot:spring-boot-starter-actuator:1.4.1.RELEASE'
    ... etc other deps
}

group = 'com.springapp'
version = '1.0-SNAPSHOT'
description = 'someproj'
java.sourceCompatibility = JavaVersion.VERSION_1_8

publishing {
    publications {
        maven(MavenPublication) {
            from(components.java)
        }
    }
}

tasks.withType(JavaCompile) {
    options.encoding = 'UTF-8'
}

Answer 1

cdi-1.0后缀是一个分类器，通常在 pom 中看到像:<classifier>cdi1.0</classifier> .据我所知，它真的只存在于 Guava 15 中，所以我会到处检查以找出违规者。一些尝试:

• 检查传递依赖。使用 gradle dependencies寻找试图拉入的东西 com.google.guava:guava:21.0和不正确的分类器。也许其中之一做错了，您可以尝试更改版本或强制执行不同的操作。希望强制不会导致too much trouble with the classifier .如果时间允许，您可以尝试查找可能不匹配的依赖项。
• 在您的 IDE 中重新启动/使缓存失效，以及清除 Gradle 缓存。
