使用 Maven 发布任务时出现 Gradle 错误

如何解决使用 Maven 发布任务时出现 Gradle 错误？

我使用的是 Gradle 版本 6.7.1，目前，在我的应用程序中，我遇到了 maven 发布任务的问题。

我们将发布任务保存在名为 (nexusgradle-1.0.5.gradlE) 的中央位置 Gradle 文件中，并通过 apply from

中心位置Gradle（nexusgradle-1.0.5.gradle）的内容如下，其中包含快照和发布的nexus repo信息以及将artefacts推送到nexus的用户凭据。

apply plugin: 'maven-publish'

publishing {
    publications {
        mavenJava(MavenPublication) {
            from components.web
        }
   }
    repositorIEs {
        maven {
            credentials {
                username 'uploader'
                password 'uploaderpassword'
            }
            println 'A message which is logged at QUIET level'
            name 'Nexus_Repo'
            def releasesRepoUrl = 'http://<hostname>/repository/<maven-releases>/'
            def snapshotsRepoUrl = 'http://<hostname>/repository/<maven-snapshots>/'
            url = project.version.endsWith('SNAPSHOT') ? snapshotsRepoUrl : releasesRepoUrl
        }
    }
}

应用程序 Gradle（子 Gradle 文件）如下所示

import org.apache.tools.ant.filters.replaCETokens

plugins {
    ID 'war'
    // Add git release plugin for versioning snaphots and release builds
    ID 'pl.allegro.tech.build.axion-release' version '1.10.1'
    ID 'org.springframework.boot' version '2.1.4.RELEASE'
    // Add Git propertIEs plugin.
    ID 'com.gorylenko.gradle-git-propertIEs' version '2.2.0'
    ID 'jacoco'
 }

// apply from center LOCATIOn
apply from :'http://<hostaname>/repository/thirdparty/com/mf/nexusgradle/1.0.5/nexusgradle-1.0.5.gradle'






repositorIEs {
        maven {
        url = 'http://<hostname>/repository/groupRepo/'
        }
    jcenter()
    }

test {
    testLogging.showStandardStreams = true
    maxParallelForks = 3

    ignore@R_651_4895@ = true // to skip test @R_651_4895@
    testLogging { //logging the test
        exceptionFormat = 'full'
        events "passed","skipped","Failed"
    }
}

jacoco {
    toolVersion = '0.8.3'
}

jacocoTestReport {
    dependsOn test // tests are required to run before generaTing the report
    reports {
        xml.enabled true //enabling for generate xml for to capture data in sonarqube server
    }
}

// Customize Git propertIEs plugin.
gitPropertIEs {
    // Change date format in git.propertIEs file.
    dateFormat = "yyyy-MM-dd HH:mm:ssZ"
    dateFormatTimeZone = 'GMT'
}

dependencIEs {
    implementation 'org.springframework.boot:spring-boot:2.1.4.RELEASE'
    // mutliple import below 
}

sourceCompatibility = '1.8'
targetCompatibility = '1.8'

scmVersion {
    repository {
        directory = project.rootProject.file('.')
    }
}

group = 'com.package'
description = 'appname'
project.version = scmVersion.version
project.ext.timestamp = new Date().format("dd/MM/yyyy HH:mm:ss")

processresources {
    filter replaCETokens,tokens:[BUILD_VERSION: project.version,BUILD_timestAMP: project.ext.timestamp]
}

tasks.withType(JavaCompilE) {
    options.enCoding = 'UTF-8'
}

war {
    enabled = true
}



springBoot {
    buildInfo()
}

bootWar {
    archiveClassifIEr = 'boot'
    mainClassname = 'com.package.appname.SpringBootRunner'
}

当我运行 Gradle 命令进行发布时

gradlew clean build publish

任务将失败，因为发布任务将尝试将快照的工件推送到发布存储库而不是快照存储库。

  > Configure project :

> Task :clean UP-TO-DATE
> Task :bootBuildInfo

> Task :publishMavenJavaPublicationToNexus_RepoRepository Failed

FAILURE: Build Failed with an exception.

* what went wrong:
Execution Failed for task ':publishMavenJavaPublicationToNexus_RepoRepository'.
> Failed to publish publication 'mavenJava' to repository 'Nexus_Repo'
   > Could not PUT 'http://<hostname>/repository/maven-releases/com/package/appname/1.0.9-SNAPSHOT/maven-Metadata.xml'. Received status code 400 from server: Repository version policy: RELEASE does not allow Metadata in path: com/package/appname/1.0.9-SNAPSHOT/maven-Metadata.xml

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --deBUG option to get more log output. Run with --scan to get full insights.

* Get more Help at https://Help.gradle.org

但是如果我删除 apply from: 项并将发布任务带到应用程序 Gradle（子 Gradle 文件）文件中，它将正常工作，构建工件被推送到快照存储库而没有任何问题。

有人可以指导我，将 Maven 发布任务放在父 Gradle 文件中时我犯了什么错误？为什么子 Gradle 无法正确解析来自父级的值

解决方法

apply plugin: 'maven-publish'


afterEvaluate {project ->
publishing {
    publications {
        mavenJava(MavenPublication) {
            from components.web
        }
   }
    repositories {
        maven {
            credentials {
                username 'uploader'
                password 'uploaderpassword!'
            }
            name 'Nexus_Repo'
              def releasesRepoUrl = 'http://<hostname>/repository/<maven-releases>/'
            def snapshotsRepoUrl = 'http://<hostname>/repository/<maven-snapshots>/'
            url = project.version.endsWith('SNAPSHOT') ? snapshotsRepoUrl : releasesRepoUrl
        }
    }
}

}

def releasesRepoUrl = 'http://<hostname>/repository/<maven-releases>/'
def snapshotsRepoUrl = 'http://<hostname>/repository/<maven-snapshots>/'
