Question

我正在尝试部署我一直在研究Heroku的Grails 3应用程序，但是我遇到了build.gradle文件的问题我认为。

以下命令在本地运行：

./gradlew stage
heroku local web

然后我可以在http://localhost:5000/

看到我的Grails应用程序

部署的第一部分显示它执行我的阶段任务。但后来，它抱怨无法找到舞台任务。

remote: -----> Gradle app detected
remote: -----> Installing OpenJDK 1.8... done
remote: -----> Building Gradle app...
remote:        WARNING: The Gradle buildpack is currently in Beta.
remote: -----> executing ./gradlew stage
remote:        Downloading https://services.gradle.org/distributions/gradle-2.13-all.zip

我在部署期间收到以下错误：

remote:  !     ERROR: Failed to run Gradle!
remote:        It looks like your project does not contain a 'stage' task, which Heroku needs in order
remote:        to build your app. Our Dev Center article on preparing a Gradle application for Heroku
remote:        describes how to create this task:

remote:        
remote:        Thanks,

但是，我已按照https://devcenter.heroku.com/articles/deploying-gradle-apps-on-heroku的说明进行操作，并已将阶段任务添加到我的build.gradle中，并且还填充了proc文件。

当我在项目的根目录中运行./gradlew任务时，舞台任务确实显示在“其他任务”下的列表中。

Other tasks

assetClean
assetPluginPackage
cleanIdeaWorkspace

这是我的build.gradle：

        classpath "com.bertramlabs.plugins:asset-pipeline-gradle:2.8.2"

task wrapper(type: Wrapper) {

}

task stage() {
    dependsOn clean, war
}
tasks.stage.doLast() {
    delete fileTree(dir: "build/distributions")
    delete fileTree(dir: "build/assetCompile")
    delete fileTree(dir: "build/distributions")
    delete fileTree(dir: "build/libs", exclude: "*.war")
}
war.mustRunAfter clean

task copyToLib(type: Copy) {
    into "$buildDir/server"
    from(configurations.compile) {
        include "webapp-runner*"
    }
}

stage.dependsOn(copyToLib)

这是我的Procfile的内容：

web: cd build ; java $JAVA_OPTS -Dgrails.env=prod -jar ../build/server/webapp-runner-*.jar --expand-war --port $PORT libs/*.war

对我做错了什么的想法？

Answer 1

我遇到了同样的问题，可以通过运行以下命令来解决

heroku config:set GRADLE_TASK="build" git push heroku master

您可以检查以下链接 https://devcenter.heroku.com/articles/deploying-gradle-apps-on-heroku

Answer 2

我正在构建一个没有测试的 jar：build -x test

所以 git push heroku master 使用后工作： heroku config:set GRADLE_TASK="build -x test"

// build.gradle.kts

tasks.jar {
    manifest {
        attributes(mapOf("Main-Class" to application.mainClass))
    }
    from(configurations.runtimeClasspath.get().map { f -> if (f.isDirectory) f else zipTree(f) })
    archiveFileName.set("cats-app.jar")
}

Answer 3

我遇到这个问题是因为我是从 master 或 main 以外的本地分支进行部署。

有关详细信息，请参阅 Heroku 文档上的 Deploying from a branch besides main，特别是：

<块引用>

如果要从本地存储库的非 main 分支（例如 testbranch）将代码部署到 Heroku，请使用以下语法确保将其推送到远程的主分支:

git push heroku testbranch:main

就我而言，我正在一个单独的分支上测试与 Heroku 的集成。我的项目已经有一个有效的 build.gradle 并且与这里的原始问题一样，我能够成功地运行 ./gradlew stage 和 heroku local，没有任何问题（因为他们正在访问更新的 {{1} } 在我当地的分支机构）。但是当我推送到 Heroku 时，我使用了命令 build.gradle，这导致了臭名昭著的：

git push heroku master

Grails 3和Heroku - 找不到阶段任务
