Android Studio項目的Gradle守護程序無法啓動

Question

好的，Android的新功能。全新安裝，Windows 10，具有空活動的基本模板項目。當我開始項目啓動同步的gradle在我家的gradle與以下錯誤

我得到同樣的錯誤，當我運行對gradlew.bat文件的基本命令的gradle開始生成日誌，但是當我首先運行set _JAVA_OPTIONS=-Djava.net.preferIPv4Stack=true，然後成功啓動守護進程。問題是，我如何使用這些信息使項目工作中的gradle同步。我已經嘗試在gradle.properties文件中添加-Djava.net.preferIPv4Stack = true，嘗試將set _JAVA_OPTIONS=-Djava.net.preferIPv4Stack=true添加到項目gradle批處理文件中，現在我沒有選擇了。

好的，終於搞明白了。我去了環境變量，並設置了一個_JAVA_OPTS用戶變量作爲值-Djava.net.preferIPv4Stack = true。
