我目前正在使用 Appium 为 iOS 构建一个测试自动化框架。在我的框架中，我在测试套件启动之前从代码内部启动 Appium 服务器（@BeforeSuite）。
当我使用命令手动运行测试时：
mvn clean test #... and so on Appium 能够启动模拟器并正常启动测试。但是，当我使用 Jenkins 以相同的目标和终端上的选项开始测试时，它无法正常工作并卡在盯着模拟器。
这是我的 Appium 服务器脚本：
#!/bin/bash
NODE='/Applications/Appium.app/Contents/Resources/node/bin/node'
APPIUM='/Applications/Appium.app/Contents/Resources/node_modules/appium/bin/appium.js'
PORT=5000
ADDR=127.0.0.1
LOGDIR=~/log
LOGFILE=$LOGDIR/appium.log
DEVICE=$(idevice_id -l |head -1)
mkdir -p $LOGDIR
function startAppium() {
SCRIPT="$NODE $APPIUM"
SCRIPT="$SCRIPT --address $ADDR \
--port $PORT \
--native-instruments-lib \
--session-override \
--backend-retries 10 \
--debug-log-spacing \
--full-reset \
--debug-log-spacing \
--command-timeout 90 \
-g $LOGFILE \
--launch-timeout 500000"
echo "Running: $SCRIPT"
$SCRIPT >> /dev/null &
}
startAppium 2>/dev/null >>/dev/null &
sleep 5
这是从 jenkins 开始时的 Appium 日志片段，当它尝试启动仪器时：

and so on...
每次 Appium 尝试重新启动模拟器时的 system.log 输出：

从 Jenkins 启动 maven 脚本时与从终端启动 maven 脚本有什么不同的权限吗？
仅供参考：Jenkins 是从当前登录的用户（jenkins）开始的，当我检查它时，进程所有者也是同一个用户。
我还尝试启动 appium 日志中提供的命令：
/Applications/Xcode.app/Contents/Developer/usr/bin/instruments -t /Applications/Xcode.app/Contents/Applications/Instruments.app/Contents/PlugIns/AutomationInstrument.xrplugin/Contents/Resources/Automation.tracetemplate -D /tmp/appium-instruments/instrumentscli0.trace -w "iPhone 5 (9.0)" /Users/Shared/Jenkins/AUT/iOS/Live-release.app -e UIASCRIPT "/Users/Shared/Jenkins/Library/Application Support/appium/bootstrap/bootstrap-f062718992d59810.js" -e UIARESULTSPATH /tmp/appium-instruments
我也尝试从jenkins内部手动运行它，当在终端上手动启动时，模拟器正常启动，但是当脚本从jenkins运行时它不会启动。
