[英]Run local Java Heroku
I'm going through the Heroku Getting Started for Java, but I'm having trouble running the example app locally. 我正在阅读《 Heroku Java入门》,但在本地运行示例应用程序时遇到了麻烦。

After I run it, I get the "starting web.1 on port 5000", but when I open localhost:5000, it just gives me "This webpage is not available." 运行它之后,我得到“在端口5000上启动web.1”,但是当我打开localhost:5000时,它只是显示“此网页不可用”。
Here is the output from CLI 这是CLI的输出
$ heroku local web -f Procfile.windows
forego | starting web.1 on port 5000
web.1 | Usage: java [-options] class [args...]
web.1 | in the version search
web.1 | show splash screen with specified image
web.1 |

UPDATE: So I actually ran the command on my own, when I realized, that's all that Procfile does, and the last line I get is 更新:所以我实际上是自己运行命令的,当我意识到这就是Procfile所做的全部,我得到的最后一行是
sh.exe": target\dependency\*: No such file or directory
When this is obviously is a target\\dependency made from mvn clean install? 这显然是由mvn全新安装造成的target \\ dependency吗? What am I typing wrong?
我打错了什么?
$ java -cp target\classes;"target\dependency\*" Main
This has a lot to do with compatibility. 这与兼容性有很大关系。
What I didn't mention, which had a lot to do with it, was that I was running this on GitBash. 我没有提到的与它有很大关系的是我在GitBash上运行它。 So it was taking everything differently.
因此,一切都与众不同。
Ex. 例如 I had to escape the semicolon for the cp argument.
我必须对cp参数使用分号进行转义。
Short story the Procfile.windows should be 简而言之,Procfile.windows应该是
web: java -cp target/classes\;target/dependency/* Main
no quotes anywhere... I'm leaving this up in case anyone else has issues 任何地方都没有报价...如果有人遇到问题,我将保留此报价
Using double quotes should have the same effect as using the backslash in this case; 在这种情况下,使用双引号应与使用反斜杠具有相同的效果。 ie
java -cp "target/classes;target/dependency/*" Main
should also work. 即
java -cp "target/classes;target/dependency/*" Main
也应该起作用。
