尝试从源代码构建Elasticsearch。

刚刚安装了OpenJAVA-11-sdk和jre。

下面是`java`和`javac`以及`echo $PATH`的输出。

# 答案1
**得分**: 3

**查看错误,似乎存在编译错误,很可能是由于JDK版本引起的,因为您的`JAVA_HOME`指向JDK 11。**

以下是解决此问题的方法:

1. 如果您已经克隆了最新的Elasticsearch源代码,从[https://github.com/elastic/elasticsearch][1],那么要构建Elasticsearch,需要JDK 14。然而,由于Elasticsearch支持JDK 11,因此构建支持使用JDK 14编译并在JDK 11运行时进行测试。

2. 安装JDK 14并将`JAVA_HOME`设置为JDK 14安装的Java主目录后,再次使用以下命令运行Elasticsearch源代码:`./gradlew :run`。

3. 一旦进程完全启动,然后在另一个窗口中运行curl,如下所示:

   `curl -u elastic:password localhost:9200`

要获取详细的解释,请参考[CONTRIBUTING.md][2]

**Looking at the errors, it seems like there is a compilation error which is most probably because of the JDK version, as your `JAVA_HOME` is pointing to JDK 11.**

Here are the ways by which you can resolve the issue : 

1. If you have cloned the latest Elasticsearch source code from [https://github.com/elastic/elasticsearch][1], then to build Elasticsearch, JDK 14 is required. However, since Elasticsearch supports JDK 11, the build supports compiling with JDK 14 and testing on a JDK 11 runtime.

2. After installing JDK 14, and setting `JAVA_HOME` pointing to Java home of JDK 14 installation, run Elasticsearch source code with this command again `./gradlew :run`.

3. Once the process is fully started, then run curl in another window like this 

`curl -u elastic:password localhost:9200`

To get a detailed explanation refer this [CONTRIBUTING.md][2]
