Gradle找不到番石榴-*版本*-cdi1.0.jar

Question

可能是显而易见的，但这个问题让我陷入了一段时间。

有些库需要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 (没有-cdi1.0后缀)存在于该路径上。为什么gradle会在文件名中添加-cdi1.0后缀，并且是否可以禁用此功能？或者我只是误解了什么，还有别的什么在起作用？

我试图单独指定guava dep，但是它不影响任何事情。

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'
}

来自gradle --debug build

然后以后：

这是调试日志Detected non-existence of artifact 'guava-30.1-jre-cdi1.0.jar (com.google.guava:guava:30.1-jre)' in resolver cache中提到cdi分类器的唯一一次，但生成失败消息除外。

Answer 1

cdi-1.0后缀是一个分类器，通常出现在pom中，如：<classifier>cdi1.0</classifier>。据我所见，它实际上只在番石榴15，所以我会检查各地，试图找到罪犯。有些事情需要尝试：

• 检查传递依赖项。使用gradle dependencies查找试图引入com.google.guava:guava:21.0和不正确分类器的内容。也许其中之一做得不对，你可以尝试改变版本或者强迫做一些不同的事情。希望强迫不会导致too much trouble with the classifier。如果时间允许，您可以尝试在您的IDE中找到可能是mismatched.
• Restart /失效缓存的依赖项，以及清除Gradle缓存.
