JetBrains Scala插件升级到v1.4后，Play项目无法运行 [英] Play project does not run after JetBrains Scala plugin ugraded to v1.4

问题描述

将IntelliJ IDEA 14中的Scala插件升级到v1.4后，我的Play项目停止运行。
它可以成功制作项目，但无法启动网络应用程序。
该项目处于工作状态数月，没有任何问题。
我注意到Scala facet现在不可用，即使我创建了一个新的Play / Scala项目。
如果你看一下主题。

After upgrading Scala plugin in IntelliJ IDEA 14 to v1.4 my Play project ceased to run. It can "make" the project successfully but cannot launch web-app. The project was in working state for months and there were no problems. I noticed that Scala facet is not available now, even if I create a new Play/Scala project. My problem is not unique if you look at the thread.

这是插件的问题还是我缺少的东西？

Is it the problem of plugin or something I am missing?

推荐答案

我遇到同样的问题，不能将插件降级到1.3.3或更低（另一个IDEA错误？）并打开一个问题

I'm experiencing same problem and can't downgrade the plugin to 1.3.3 or lower (another IDEA bug? ) and opened an issue

我很确定这是IDEA / Plugin方面的问题，因为您仍然可以使用激活器在IDEA中运行和调试您的应用程序：

I'm pretty sure it's an issue on IDEA/Plugin side since you still can run and debug your application in IDEA with activator:

在Play2应用程序的目录中运行它

Run it in directory of your Play2 application

• 在DEV模式下运行激活器运行RUN_PORT


• 在PROD模式下运行激活器启动START_PORT


• 调试 activator -jvm-debug DEBUG_PORT运行RUN_PORT

• to run in DEV mode activator run RUN_PORT
• to run in PROD mode activator start START_PORT
• to debug activator -jvm-debug DEBUG_PORT "run RUN_PORT"

用您的端口替换PORT（通常RUN_PORT为9000，DEBUG_PORT为9999）。

Substitute PORTs with your ports (usually RUN_PORT is 9000 and DEBUG_PORT is 9999).

用于在IDEA中进行调试：

For debugging in IDEA:

1. 创建新配置菜单运行 - >编辑配置...


2. 点击+符号添加新配置，然后在下拉列表中选择远程。


3. 设置配置是默认的（传输：套接字，调试器模式：附加）


4. 输入运行应用程序的主机和调试端口（使用DEBUG_PORT 9999在本地运行 - >输入localhost和9999 ）


5. 创建此配置后，选择它并按Debug按钮。

1. create new configuration "Menu Run -> Edit configuration..."
2. click on "+" sign "Add new configuration" and choose "Remote" in drop-down list.
3. Settings of configuration are default (Transport: Socket, Debugger mode: Attach)
4. Enter host and debug port where your app is running (running locally with DEBUG_PORT 9999 -> enter "localhost" and "9999")
5. After creating this configuration select it and press Debug button.
