使用eclipse 编译elasticsearch 7.6.4小结

今天花了不少时间，编译好了elasticsearch 7.6.4，简单总结如下：

需要安装jdk 13
测试代码使用了com.sun.net.httpserver.HttpExchange ，因此需要关闭限制 “Access restriction on class due to restriction on required library rt.jar”，执行如下动作：
On Windows: Windows -> Preferences -> Java -> Compiler -> Errors/Warnings -> Deprecated and restricted API -> Forbidden reference (access rules): -> change to warning
On Mac OS X/Linux: Eclipse -> Preferences -> Java -> Compiler -> Errors/Warnings -> Deprecated and restricted API -> Forbidden reference (access rules): -> change to warning

项目中大量循环依赖，需要执行以下动作
Mark circular dependencies as “Warning” in Eclipse tool to avoid “A CYCLE WAS DETECTED IN THE BUILD PATH” error.
In Eclipse go to:
Windows -> Preferences -> Java-> Compiler -> Building -> Circular Dependencies
默认过程中测试需要很长时间，如果不等待可以在build.gradle 增加如下代码，跳过（同时也无法执行）测试

//skip Test tasks
gradle.taskGraph.whenReady {
        tasks.each { task ->
            if (task.name.contains("test"))
            {
                task.enabled = false
            }
            if (task.name.contains("integTest"))
            {
                task.enabled = false
            }
            
        }
}

5.还需要确认使用utf-8 编码（不关键，影响少量测试代码）

6.最后注意编译需要下载大量第三方jar，在src生成后可以考虑手工设置一些国内镜像repository
