java - 为什么将 gradle java 应用程序部署到 heroku 失败？

Question

我正在尝试从本地计算机将 gradle java 应用程序部署到 heroku。我的项目包含以下文件

我在 build.gradle 中定义了以下任务

task stage {
  dependsOn build
}

task wrapper(type: Wrapper) {
    gradleVersion = '2.12'
}

ProcFile的内容如下:

web: java -Dserver.port=$PORT $JAVA_OPTS -jar target/demo-0.0.1-SNAPSHOT.jar

执行git commit heroku master时出现以下错误

执行git ls-files gradle时列出以下文件

您能否告诉我为什么在将应用程序部署到 Heroku 服务器时出现错误？

Answer 1

If you are using gradlew, then you must also add your gradle/wrapper/gradle-wrapper.jar and gradle/wrapper/gradle-wrapper.properties to your Git repository. If you do not add these files, you will receive an error such as:

-----> executing ./gradlew stage
       Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain

并解决它:

You can add the wrapper files by running these commands:

git add gradle/wrapper
git commit -m "Gradle Wrapper"
