本地Google Cloud Appengine無法啟動

Question

我正在嘗試從Google的Google Cloud Appengine（ https://github.com/GoogleCloudPlatform/getting-started-java/tree/master/appengine-standard-java8/helloworld ）運行入門示例。 盡管該部署可以運行並且可以在Google Cloud中運行，但是我無法為本地Java appengine模擬器啟動它。 Google SDK是最新的（231），Maven 3.5，Java8。我嘗試以“ mvn appengine：run”開頭

Answer 1

我現在自己發現了錯誤。 它根本無法與JAVA_HOME中的“ java-ibm-x86_64-80”一起使用。 我現在改為使用“ java-8-openjdk-amd64”作為JAVA_HOME，現在沒有任何問題了。
