「無法運行在模擬器應用程序」，從TeamCity的生成代理

Question

我看到這個錯誤在我的TeamCity生成代理輸出：

...

如果我直接在生成代理機器上運行完全相同的命令：

$ /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -project Foobar/Foobar.xcodeproj -scheme foobarNightly SYMROOT=/Users/Me/buildAgent/work/e60c5dca158b2d23/Foobar/build OBJROOT=/Users/Me/buildAgent/work/e60c5dca158b2d23/Foobar/build test -sdk iphonesimulator8.1 

它的工作原理。任何想法爲什麼這從TeamCity構建代理失敗？

Answer 1

好吧，看起來我們已經找出了真正的問題。隨TeamCity提供的plist文件包含屬性，對於最新的Mac OS X版本，該屬性不應該存在。

問題應固定在TeamCity的9.0.4，但作爲一種解決方法，你應該把jetbrains.teamcity.BuildAgent.plist到 ~/Library/LaunchAgents/jetbrains.teamcity.BuildAgent.plist 並拆除屬性和值。

jetbrains.teamcity.BuildAgent.plist文件目前的變化是：

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>WorkingDirectory</key> <string>/agent/home/directory</string> <key>Debug</key> <false/> <key>Label</key> <string>jetbrains.teamcity.BuildAgent</string> <key>OnDemand</key> <false/> <key>KeepAlive</key> <true/> <key>ProgramArguments</key> <array> <string>bash</string> <string>--login</string> <string>-c</string> <string>launcher/bin/TeamCityAgentService-macosx-universal-32 -c ../conf/wrapper.conf</string> </array> <key>RunAtLoad</key> <true/> <key>StandardErrorPath</key> <string>logs/launchd.err.log</string> <key>StandardOutPath</key> <string>logs/launchd.out.log</string> </dict> </plist>

每TeamCity的的documentation，有兩種方法可以在OS X創建構建代理守護程序：

• 系統範圍：/Library/LaunchDaemons/jetbrains.teamcity.BuildAgent.plist
• 用戶專用：~/Library/LaunchAgents/jetbrains.teamcity.BuildAgent.plist

原來這兩個選項都不會讓允許TeamCity構建代理啓動Xcode模擬器。

如果構建代理手動啓動後直接（不SSH）登錄到生成代理機：

$ sh buildAgent/bin/agent.sh start 

的TeamCity的生成代理將能夠啓動模擬器。要在啓動時運行此腳本，請使用Automator創建一個.app：https://stackoverflow.com/a/6445525/429533
