Question

我正在尝试为Heroku平台配置Procfile文件以在本地运行应用程序。我正在尝试运行基于Tomcat的Java Web应用程序。

在教程中他们说：

To build your app locally do this:
Use the Git Bash application to open a command shell on Windows.
$ mvn clean install
$ heroku local web

我在项目目录中，在收到mvn clean install之后

BUILD SUCCESS

问题出在我运行时：heroku local web 我收到了[WARN] No ENV file found web.1 | Error: Could not find or load main class $JAVA_OPTS

我的Procfile有1行：

web：java $ JAVA_OPTS -jar target / dependency / webapp-runner.jar --port $ PORT target / * .warz

我正在使用Windows。我在堆栈上看到post，他们说Procfile中Windows上的代码是不同的。它应该看起来像这样（我的创作）：

web：java％JAVA_OPTS％-jar target \ dependency \ webapp-runner.jar --port％PORT％target * .war

我必须在目标文件夹中创建一个名为“dependency”的文件夹？因为我的项目中没有webbapp-runner.jar，我不明白该怎么做。

这是我的pom.xml

我应该将webapp-runner添加为插件吗？

Answer 1

您需要像这样添加webapp-runner到您的Sub MakeUnboldedTextBlue() ' ' MakeUnboldedTextBlue Macro ' ' Selection.Find.ClearFormatting Selection.Find.Font.Bold = False With Selection.Find .Text = "" .Replacement.Text = "" .Forward = True .Wrap = wdFindAsk .Format = True .MatchCase = False .MatchWholeWord = False .MatchKashida = False .MatchDiacritics = False .MatchAlefHamza = False .MatchControl = False .MatchWildcards = False .MatchSoundsLike = False .MatchAllWordForms = False End With Selection.Font.Color = 15773696 End Sub：

pom.xml

然后您的<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <version>2.3</version> <executions> <execution> <phase>package</phase> <goals><goal>copy</goal></goals> <configuration> <artifactItems> <artifactItem> <groupId>com.github.jsimone</groupId> <artifactId>webapp-runner</artifactId> <version>8.5.11.2</version> <destFileName>webapp-runner.jar</destFileName> </artifactItem> </artifactItems> </configuration> </execution> </executions> </plugin>可能如下所示：

Procfile

你的web: java $JAVA_OPTS -jar target/dependency/webapp-runner.jar --port $PORT target/*.war可以看起来像这样：

Procfile.windows

Answer 2

所以我在stackoverflow上阅读了很多有关Heroku的错误+教程的帖子，并没有找到解决方案，但我做了一些改进。我阅读了this post并删除了<pluginManagement>中的开始<pluginManagement/>和结束pom.xml标记，现在创建了dependency目录和webapp-runner-8.0.30.1.jar。我的应用程序正在运行，因为如果我使用Tomcat在Eclipse中运行我的应用程序，我可以访问localhost：8080 / login，我可以看到我的网站。我跑的时候：

mvn package

我收到build succes，然后我在cmd中运行

java -jar target / dependency / webapp-runner.jar target / * .war

我收到：error invalid or corrupt jarfile target/dependency/webapp-runner.jar

这是我的Procfile：

web：java $ JAVA_OPTS -jar target / dependency / webapp-runner.jar --port $ PORT目标/ * .war

这是我的Procfile.windows：

web：java％JAVA_OPTS％-jar target \ dependency \ webapp-runner.jar --port％PORT％target * .war
