Gradle 无法解析私有 Nexus 3 存储库的依赖关系

Question

我正在尝试构建一个使用私有 Nexus 存储库中的库的 gradle 项目。

版本：

• Gradle 7.4
• Nexus OSS 3.37

这是 build.gradle：

plugins {
    id 'java'
}

group 'io.riccardopedrielli'
version '1.0.0'

repositories {
    maven {
        url 'https://nexus.riccardopedrielli.io/repository/maven-releases/'
        credentials {
            username '<myuser>'
            password '<mypass>'
        }
    }
    mavenCentral()
}

dependencies {
    implementation 'io.riccardopedrielli.mylib:1.0.0'
}

当我运行 ./gradlew build 时，出现以下错误：

* What went wrong:
Execution failed for task ':compileJava'.
> Could not resolve all files for configuration ':compileClasspath'.
   > Could not find io.riccardopedrielli.mylib:1.0.0:.
     Required by:
         project :

添加 --debug 我看到这些与 lib 相关的行：

[org.gradle.api.internal.artifacts.ivyservice.resolveengine.graph.builder.NodeState] dependency: io.riccardopedrielli.mylib:1.0.0 from-conf: implementation to-conf: null is filtered.

相反，如果我将 maven 与以下 pom.xml 一起使用，则一切正常：

<?xml version="1.0" encoding="UTF-8"?>
<project
    xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>io.riccardopedrielli</groupId>
    <artifactId>myapp</artifactId>
    <version>1.0.0</version>

    <dependencies>
        <dependency>
            <groupId>io.riccardopedrielli</groupId>
            <artifactId>mylib</artifactId>
            <version>1.0.0</version>
        </dependency>
    </dependencies>

    <repositories>
        <repository>
            <id>central</id>
            <url>http://repo1.maven.org/maven2</url>
        </repository>
        <repository>
            <id>localNexus</id>
            <url>https://nexus.riccardopedrielli.io/repository/maven-releases/</url>
        </repository>
    </repositories>

    <build>
        ...
    </build>

    <properties>
        ...
    </properties>
</project>

由于 Nexus 存储库与 maven 兼容，我想我错过了某物在build.gradle中。

尝试在maven中添加metadataSources，如下例所示：

maven {
   url = uri("nexus-maven-url")
    metadataSources
    {
        mavenPom();
        artifact()
    }
   }
}
