如何为 gradle 发布任务设置超时？答案

【问题描述】：

我使用“gradle publish”命令发布到nexus repo。

配置如下：

publishing {
    publications {
        maven(MavenPublication) {
            groupId = 'org.gradle.sample'
            artifactId = 'library'
            version = '1.1'

            from components.java
        }
    }
}

任务超时可以这样设置：

task someTask {
    timeout = Duration.ofMinutes(25)
}

我想为发布配置部分生成的所有发布任务（我认为发布配置生成更多任务）设置超时。像这样的东西似乎不起作用：

publishing {
    publications {
        maven(MavenPublication) {
            groupId = 'org.gradle.sample'
            artifactId = 'library'
            version = '1.1'

            from components.java

            timeout = Duration.ofMinutes(25)
        }
    }
}

【解决方案1】：

Task publish 是一个没有操作的聚合任务。它将根据您的配置生成一个名为publishPubNamePublicationToRepoNameRepository 的任务，并替换PubName。您可以使用--dry-run 来查找它生成的任务：

$ gradle publish --dry-run
:compileJava SKIPPED
:processResources SKIPPED
:classes SKIPPED
:jar SKIPPED
:generateMetadataFileForMavenPublication SKIPPED
:generatePomFileForMavenPublication SKIPPED
:publishMavenPublicationToMavenRepository SKIPPED
:publish SKIPPED

所以我的配置会生成一个发布任务publishMavenPublicationToMavenRepository。然后我可以找到那个任务并设置它的超时时间：

plugins {
    id("java")
    id("maven-publish")
}

project.afterEvaluate {
    tasks.findByName("publishMavenPublicationToMavenRepository").configure {
        timeout = Duration.ofMillis(1)
    }
}

注意tasks.findByName 被放入project.afterEvaluate 块中，因为publish 动态生成该任务。

这是预期的结果：

$ gradle publish

> Task :publishMavenPublicationToMavenRepository FAILED
Requesting stop of task ':publishMavenPublicationToMavenRepository' as it has exceeded its configured timeout of 1ms.
