【中文标题】gradle publish 不拾取工件：“尽管执行了操作，但任务尚未声明任何输出。”

【英文标题】：gradle publish does not pick up artifacts: "Task has not declared any outputs despite executing actions."

【问题描述】：

我正在将一个 java 项目从 gradle 2.x 迁移到 5.3.1。

最后一个问题是没有人工制品（在我们的例子中是 tar）被发布到人工制品。

main build.gradle 中的配置是

subprojects 
    apply plugin: "com.jfrog.artifactory"
    project.ext 
        artifactoryConfig = new File(project.gradle.gradleUserHomeDir, "artifactory.gradle")
    
    if (artifactoryConfig.exists()) 
        apply plugin: 'maven'
        apply from: artifactoryConfig
    
    sourceCompatibility = 1.8
    repositories 
        mavenCentral()
        maven  url $OUR_ARTIFACTORY 
    
    publishing 
        publications 
            mavenJava(MavenPublication) 
                from components.java
            
        
    

artifactory 
    publish 
        contextUrl = "$artifactoryBaseUrl"
        repository 
            repoKey = "libs-release-local"
            username = "$artifactoryUsername"
            password = "$artifactoryPassword"
        
    
    resolve 
        repoKey = 'repos'
    

在模块中

task('dist', type: Tar) 
    dependsOn('jar')
    archiveName "$MODULE-$version.$extension"
...

publishing 
    publications 
        mavenJava(MavenPublication)
                
                    artifact dist 
                    
                
    

configurations.archives.artifacts.clear()
artifacts 
    archives dist

现在，当我执行 ./gradlew --info :$MODULE:artifactoryPublish 时，它会抱怨缺少输出并且不会将 tar 发布到工件。

如何解决这个问题？

> Task :$MODULE:artifactoryPublish
Task ':$MODULE:artifactoryPublish' is not up-to-date because:
  Task has not declared any outputs despite executing actions.
:$MODULE:artifactoryPublish (Thread[Execution worker for ':',5,main]) completed. Took 0.002 secs.
:artifactoryDeploy (Thread[Execution worker for ':',5,main]) started.

> Task :artifactoryDeploy
Task ':artifactoryDeploy' is not up-to-date because:
  Task has not declared any outputs despite executing actions.
Deploying build descriptor to: $OUR_ARTIFACTORY/artifactory/api/build
Build successfully deployed. Browse it in Artifactory under $OUR_ARTIFACTORY/artifactory/webapp/builds/$MODULE/1554465369336
:artifactoryDeploy (Thread[Execution worker for ':',5,main]) completed. Took 0.155 secs.

【问题讨论】：

关于“它抱怨缺少输出”：这对我本身来说并不可疑，因为所讨论的任务没有任何基于文件的输出。 Artifactory 上实际部署了什么？我问是因为它说：“构建成功部署。”

@Chriki 没有将任何内容部署到工件（构建为空）。这就是问题所在。

运气好吗？

@Abhimaan 是的；查看接受的答案。

【参考方案1】：

对我来说，问题是 url 和凭据为空。它导致了相同的错误消息（任务未声明任何输出）。

artifactory 
    contextUrl = artifactoryUrl

    publish 
        repository 
            username = artifactoryPublishUser
            password = artifactoryPublishPassword

【参考方案2】：

最有价值的提示是运行示例

https://github.com/jfrog/project-examples/tree/master/gradle-examples/gradle-android-example

【参考方案3】：

原来解决方案是添加

artifactoryPublish 
    publications('mavenJava')
