在IntelliJ IDEA中构建和运行Elasticsearch源代码时出错

Question

我想将Elasticsearch源代码导入并运行到IntelliJ IDEA项目中，为此：

1. 我已经从官方Github存储库中克隆了最新的Elasticsearch源代码https://github.com/elastic/elasticsearch.

JAVA_HOME设置为/home/bhavya/.jenv/versions/11

2. 然后我将项目导入IntelliJ IDEA

3. 现在，当我使用build.gradle从IntelliJ IDEA运行弹性搜索时，会生成以下响应

4. 现在，根据CONTRIBUTING.md，当我从终端使用命令./gradlew :run运行Elasticsearch时，我得到以下错误：

错误

注意：当JAVA_HOME设置为/home/bhavya/.jenv/versions/14时，我在尝试使用./gradlew :run运行Elasticsearch时出现以下错误

Unrecognized VM option 'AggressiveOpts'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

有人能帮我解决这个问题吗？

Answer 1

我在弹性搜索方面也遇到了同样的问题。解决方案是将Java升级到openjdk-14-jdk或Java-15-orace。

两人都为我做了
