谷歌应用程序引擎端点版本迁移V1到V2

Question

我们使用android studio创建了Google Endpoint api v1。我们收到了来自谷歌云的电子邮件，即谷歌Api版本v1已被弃用。所以我们尝试将v1更新为v2。因此，请参阅下面的迁移链接。https://cloud.google.com/endpoints/docs/frameworks/legacy/v1/java/migrating-android#before_you_begin

在改变之后，当我们试图运行时间节目时/后端/构建/分解的应用程序"不存在

如果我查看项目中的目录树我可以看到基于模块名称"backend"和包含发现文档的"endpointsDiscoveryDocs"的分解目录"../build/分解的backend"。

不可用'/后端/构建/分解的应用和'/backend/build/endpointsClientLibs'

当我尝试执行时，Build成功了，但显示在运行后端时出错：无法启动进程，工作目录"…"。。。\MyAppliaiton\backend\build\explorated app'不存在

以下build.xml用于我的android项目

MyApplication build.gradle

buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.google.guava:guava:19.0'
classpath 'com.android.tools.build:gradle:2.3.3'

}
allprojects {
repositories {
jcenter()
}
}

delete rootProject.buildDir

我需要帮助这里发生的事情。

Answer 1

我正在将我的appengine模块从Java 7更新到Java 8，并将端点v1更新到端点v2，这真的很痛苦。

我已经解决了去的问题

[后端模块]/[后端模块].iml

并更改行

value="C:\workspace\[project]\[backend-module]\build\分解的应用

到

value="C:\workspace\[project]\[backend-module]\build\explored-[backend-module]
