maven无法在应用程序引擎标准环境上构建“适用于Java的书架应用程序”，例如来自谷歌的pom问题。xml？
我正在尝试在app engine上获得Java书架应用程序 “https://cloud.google.com/java/getting-started-appengine-standard/tutorial-app”
我已经完成了为我的项目设置账单、启用API和下载SDK等所有步骤
我克隆了回购协议
git克隆https://github.com/GoogleCloudPlatform/getting-started-java.git
然后我开始跑步
mvn -Plocal clean appengine:devserver
从目录中
getting-started-java/bookshelf-standard/2-structured-data
这就是事情变得奇怪的地方。在波姆。当我将appengine maven插件和appengine-api-1.0-sdk版本设置为最新版本1.9.73时
我明白了
Error opening zip file or JAR manifest missing : /home/anirudh/.m2/repository/com/google/appengine/appengine-java-sdk/1.9.73/appengine-java-sdk/appengine-java-sdk-1.9.73/lib/agent/appengine-agent.jar
现在我尝试使用一个旧版本的maven插件和appengine-api-1.0-sdk
我无法创建DevAppserver
