“无法运行在模拟器应用程序”，从TeamCity的生成代理

Question

我看到这个错误在我的TeamCity生成代理输出：

...

如果我直接在生成代理机器上运行完全相同的命令：

$ /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。任何想法为什么这从TeamCity构建代理失败？

Answer 1

好吧，看起来我们已经找出了真正的问题。随TeamCity提供的plist文件包含属性，对于最新的Mac OS X版本，该属性不应该存在。

问题应固定在TeamCity的9.0.4，但作为一种解决方法，你应该把jetbrains.teamcity.BuildAgent.plist到 ~/Library/LaunchAgents/jetbrains.teamcity.BuildAgent.plist 并拆除属性和值。

jetbrains.teamcity.BuildAgent.plist文件目前的变化是：

<?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>

Answer 2

每TeamCity的的documentation，有两种方法可以在OS X创建构建代理守护程序：

• 系统范围：/Library/LaunchDaemons/jetbrains.teamcity.BuildAgent.plist
• 用户专用：~/Library/LaunchAgents/jetbrains.teamcity.BuildAgent.plist

原来这两个选项都不会让允许TeamCity构建代理启动Xcode模拟器。

如果构建代理手动启动后直接（不SSH）登录到生成代理机：

$ sh buildAgent/bin/agent.sh start 

的TeamCity的生成代理将能够启动模拟器。要在启动时运行此脚本，请使用Automator创建一个.app：https://stackoverflow.com/a/6445525/429533
