Presto 0.227版本源码编译

1. 环境准备

（1）Win10

（2）JDK（要求1.8.151及以上）

（3）Maven（要求3.3.9及以上）

2. 问题出现的原因及解决方法

（1）Error: java: RegexpMultiline: Line contains carriage return

原因：Presto会对代码规范进行严格的检查，maven-checkstyle-plugin检查失败就会报错

解决方法：在presto-root模块的pom.xml中properties部分添加以下内容：

<air.check.skip-extended>true</air.check.skip-extended>

并且注释掉

<air.checkstyle.config-file>src/checkstyle/presto-checks.xml</air.checkstyle.config-file>

（2）Failed to execute goal io.takari.maven.plugins:presto-maven-plugin:0.1.12:generate-service-descriptor (default-generate-service-descriptor) on project presto-jmx: Execution default-generate-service-descriptor of goal io.takari.maven.plugins:presto-maven-plugin:0.1.12:generate-service-descriptor

原因：Presto Github上说明了它支持Linux / Mac 编译，在Windows上编译需要去掉一部分内容

解决方法：在presto-docs模块中注释掉以下内容：

                </dependencies>
            </plugin>
           

（3）IDEA报错Could not reserve enough space for xxxxKB object heap

原因：IDEA堆内存分配不够

解决方法：打开IDEA安装目录下bin中的idea.exe.vmoptions和idea64.exe.vmoptions，修改Xmx和Xms为1024m
