使用 S3 Bucket 作为带有 gradle 的 Maven 私有存储库

Question

我正在尝试使用 AWS S3 作为 maven 私有仓库..下面是我的 build.gradle 看起来像-：

import java.util.regex.Matcher
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.profile.ProfileCredentialsProvider;

buildscript {

repositories {
    mavenCentral()
}
dependencies {
    classpath 'com.amazonaws:aws-java-sdk-core:1.11.5' 
}
}



plugins {
id "java"
id "idea"
id "eclipse" //run "./gradlew cleanEclipse eclipse" after importing to eclipse
id "maven-publish"
id "maven"
id 'base'
id 'signing'
id 'jacoco'
id "net.researchgate.release" version "2.4.1"
id "org.springframework.boot" version "1.5.2.RELEASE"
}

def fetchAwsCredentials = {
try {
    return new ProfileCredentialsProvider().getCredentials()
} catch (Exception e) {
    logger.debug('Unable to retrieve AWS credentials from profile, publishing to S3 will not be available.', e)
        return null
}
}

AWSCredentials awsCredentials =  fetchAwsCredentials()


repositories {
mavenCentral()
maven {
url 'xxxxxxxx/<Bucket-Name>/snapshots/'
credentials(AwsCredentials) {
               accessKey awsCredentials.AWSAccessKeyId
               secretKey awsCredentials.AWSSecretKey
}
}
}


publish {
dependsOn assemble
}


publishing {
publications {
    maven(MavenPublication) {
        groupId this.properties['group']
        artifactId this.properties['mavenArtifactId']
        from components.java
    }
}
repositories {
    maven {
        name 'repo'
        credentials(AwsCredentials) {

              accessKey awsCredentials.AWSAccessKeyId
              secretKey awsCredentials.AWSSecretKey

        }
        if (project.version.endsWith('-SNAPSHOT')) {
            url "xxxxxxxx/<Bucket-Name>/snapshots/"
        } else {
            url "xxxxxxxx/<Bucket-Name>/releases/"
        }
    }


}

}   

但我得到以下错误

看起来它失败是因为在 gradle jar- 中添加了不正确的条件：

https://github.com/gradle/gradle/blob/master/subprojects/resources-http/src/main/java/org/gradle/internal/resource/transport/http/HttpClientConfigurer.java

任何线索？

您面临的问题是错误的 S3 Url 模式。

有两个接口从基本Credentials接口扩展。

• AwsCredentials
• 密码凭证

当您使用 时url 'xxxxxxxx/<Bucket-Name>/snapshots/'，它会将 Maven 存储库检测为普通 url。这就是为什么它要求PasswordCredentials.

你应该使用s3://<bucket-name>.s3-eu-west-1.amazonaws.com. 在这里它会要求AwsCredentials.

恕我直言，您应该为发布和快照使用两个不同的存储桶。

repositories {
    maven {
        name 'repo'
        credentials(AwsCredentials) {
            accessKey awsCredentials.AWSAccessKeyId
            secretKey awsCredentials.AWSSecretKey
        }
        if (project.version.endsWith('-SNAPSHOT')) {
            url "s3://<bucket-name>-snapshots.s3-eu-west-1.amazonaws.com"
        } else {
            url "s3://<bucket-name>-releases.s3-eu-west-1.amazonaws.com"
        }
    }
}
