java - 更新Google App Engine的Gradle版本

Question

我正在尝试在Google Cloud App Engine上运行Java应用程序，但出现以下错误:org.gradle.api.GradleException: Spring Boot plugin requires Gradle 4.0 or later. The current version is Gradle 2.12
我尝试更新gradle-wrapper.properties以使用gradle 4.5.1，并上传了自己的gradle-wrapper.jar
gradle-wrapper.properties

#Tue Apr 17 09:15:25 SGT 2018
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.5.1-all.zip

我尝试运行gradle init --type java-library来更新版本，还尝试了gradle appengineBuild和gradle appengineDeploy，但是它们都使用--stacktrace标记给出相同的错误消息。

我也尝试重新启动该项目，但是当我运行gradle init --type java-library命令启动一个新项目时，它将安装2.12版本

有谁知道如何解决这个问题？

完整的错误消息:

marketing@online-marketing-buddy:~$ gradle appengineStage --stacktrace

编辑

我使用了以下教程:Using Gradle和Gradle

通过这两个教程，我得到相同的最终结果，这就是错误。
我尝试使用以下命令更改gradle版本:

gradle wrapper --gradle-version 4.7 init --type java-application

这里的错误是:Execution failed for task ':init'. > The requested build setup type 'java-application' is not supported.。如果已经设置了项目，则在运行此命令时会给出原始错误。

所以我尝试使用--type basic，但这也给了我原始错误。

尝试gradlew时出现以下错误:

    marketing@online-marketing-buddy:~/OnlineMarketingBuddyDB_AppEngine$ ./gradlew.bat 
-bash: ./gradlew.bat: Permission denied

我不知道下一步该怎么做。

Answer 1

我遇到了同样的问题，并且按照以下步骤进行了修复:

按照Gradle in AE standard environment guide进行操作，直到“使用开发服务器测试应用程序”步骤3(不包括)。

在Google Cloud Shell中，转到/opt/文件夹并执行rm -rf gradle以卸载Gradle 2.12版。在您的应用程序文件夹中删除gradle，gradle.w和.gradle。您在这里可能会有所不同。

从here下载所需的兼容版本。

在两个位置解压缩新的Gradle版本:/opt/和您的应用程序文件夹。您将需要sudo文件夹中的/opt/权限才能执行任何操作。例如:sudo unzip gradle-4.5.1-bin.zip

将两个位置的Gradle安装文件夹名称都更改为gradle。例如:sudo mv gradle-4.5.1 gradle。

在您的应用程序文件夹中运行gradle appengineRun。
