工头找不到$ JAVA_OPTS [英] Foreman cannot find $JAVA_OPTS

问题描述

[

开始使用java＃run-the-app-locally] [1]rel =nofollow noreferrer> https://devcenter.heroku.com/articles/getting-started-with-java#run-the

如果我执行该指令，foreman会抛出以下错误：

错误：找不到Java类$ JAVA_OPTS

我已经声明了一个如下所示的env变量：

 名称变量：JAVA_OPTS 
 
变量值：-Xms256m -Xmx512m 
  

工头试图执行的Proc文件包含以下内容：

  web：java $ JAVA_OPTS -cp target / classes：target / dependency / * Main 
  

Im clueless关于发生了什么事。

注意：我已经检查了其他一些问题

使用JAVA_OPTS env变量运行java

工头立即终止

工头找不到java

编辑：我在下面回答了我自己的问题

解决方案

我怀疑你在Windows上运行。如果是这样，那么您必须像％JAVA_OPTS％一样引用JAVA_OPTS变量。但是Heroku仍然需要* nix风格（ $ JAVA_OPTS ），所以我建议在*之后创建一个 Procfile.win 您的 Procfile 包含以下内容：

  web：java％JAVA_OPTS％ -cp target / classes：target / dependency / * Main 
  

然后运行以在本地启动您的应用程序：

  $ foreman start --procfile = Procfile.win 
  

I have an error following the next tutorial from Heroku specifically on this part

[https://devcenter.heroku.com/articles/getting-started-with-java#run-the-app-locally][1]

If I execute that instruction foreman throws the following error:

Error: cannot find java class $JAVA_OPTS

I have already declared a env variable like this:

Name variable : JAVA_OPTS

Variable value: -Xms256m -Xmx512m

The Proc file that foreman is trying to execute has the following:

web:    java $JAVA_OPTS -cp target/classes:target/dependency/* Main

Im clueless about what is happening.

Note: I already checked some other questions

Running java with JAVA_OPTS env variable

Foreman terminates immediately

foreman can't find java

Hope someone knwos what is happening.

EDIT : I answered my own question below

解决方案

I suspect you are running on Windows. If so, then you'll have to reference the JAVA_OPTS var like %JAVA_OPTS%. But Heroku will still need the *nix style ($JAVA_OPTS), so I recommend creating a Procfile.win next to your Procfile with the following contents:

web: java %JAVA_OPTS% -cp target/classes:target/dependency/* Main

Then run this to start your app locally:

$ foreman start --procfile=Procfile.win
