由于我没有Gradle版本和源代码8，Gradle构建失败

Question

我正在尝试构建和运行一个项目，但我收到了这些错误/警告。文档说它需要JVM 10和Gradle 6:

D:GITgeospring-boot>.gradlew  bootRun
> Task :compileJava FAILED
D:GITgeospring-bootsrcmainjavamodule-info.java:1: error: modules are not supported in -source 
8
module Geo {
^
(use -source 9 or higher to enable modules)
1 error

我看到这个消息：use -source 9 or higher to enable modules然而，它看起来像是在使用java10

D:GITgeospring-boot>java -version
openjdk version "10" 2018-03-20
OpenJDK Runtime Environment 18.3 (build 10+44)
OpenJDK 64-Bit Server VM 18.3 (build 10+44, mixed mode)

我还看到了以下消息：Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.但看起来我使用的是Gradle 2.2

D:GITgeospring-boot>.gradlew -v

您需要在构建脚本中设置版本

compileJava {
options.release = 10
}
