我正在尝试构建这个项目来开发自定义x-pack插件（https://github.com/elastic/shield-custom-realm-example）

但是，当我尝试./gradlew在项目根目录中运行时，JAVA_HOME must be set to build Elasticsearch出现错误。

以下是有关为什么我不明白为什么会引发此错误的详细信息。

➜  shield-custom-realm-example git:(master) echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk-10.0.1.jdk/Contents/Home
➜  shield-custom-realm-example git:(master) java -version
'java version "10.0.1" 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)
➜  shield-custom-realm-example git:(master) ./gradlew

> Configure project :
Project evaluation failed including an error in afterEvaluate {}. Run with --stacktrace for details of the afterEvaluate {} error.


FAILURE: Build failed with an exception.

* Where:
Build file '~/dev/temp/shield-custom-realm-example/build.gradle' line: 39

* What went wrong:
A problem occurred evaluating root project 'x-pack-custom-realm-extension-example'.
> Failed to apply plugin [id 'elasticsearch.build']
   > JAVA_HOME must be set to build Elasticsearch

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

Deprecated Gradle features were used in this build, making it incompatible with Gradle 5.0.
See https://docs.gradle.org/4.5/userguide/command_line_interface.html#sec:command_line_warnings

此外，我还将这些添加到我的~/.zshrc文件中。

export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk-10.0.1.jdk/Contents/Home"
export RUNTIME_JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk-10.0.1.jdk/Contents/Home"

尝试运行./gradlew --stop，确认env | grep JAVA您的环境变量已导出并再次尝试构建。过去在我身上发生过 Gradle 守护进程在没有 env var 的情况下启动并且没有重新启动以获取它。
