我正在閱讀Google App Engine for Java中的「Hello World」教程。一切工作正常,當我通過執行運行在瀏覽器中的應用:在Intellij中調試Google App Engine應用程序
mvn appengine:devserver
在我的瀏覽器我剛剛推出:
http://localhost:8080
但在的IntelliJ,當我運行調試,在瀏覽器中打開,但網頁無法顯示(錯誤403)。
我認爲問題與Intellij中項目的配置方式有關。見我的調試設置附截圖:
這是我不太清楚,當我鍵入它,當我從的IntelliJ運行哪一個使用Maven的命令正在使用什麼應用程序服務器。 Intellij似乎使用Jetty。這是在的IntelliJ的應用程序服務器設置的快照:

我怎樣才能解決這個問題,這樣我可以在運行的IntelliJ調試?
我做了你指出的更改,但是當我運行調試時,我得到:運行調試本地應用程序引擎時出錯:無法打開調試器端口(localhost:5005):java.net.ConnectException「連接被拒絕」 - 是否需要安裝某種權限?我在Mac上運行這個。 – AndroidDev
你有沒有可能阻擋它的防火牆?你的mvn輸出是否顯示類似於'在地址:5005'偵聽傳輸dt_socket? – tx802
我懷疑防火牆正在阻止它,因爲命令mvn appengine:devserver起作用。但我不確定端口5005是否被阻塞。我沒有看到任何Maven輸出,因爲我在IDE中運行它。 – AndroidDev
