今天maven install时碰到的两个问题（堆溢出和编译错误）

Posted 2020-07-16 Fight With Me!!!

问题1.maven install时出现，日志如下：

系统资源不足。
有关详细信息，请参阅以下堆栈追踪。

原因分析：虚拟机堆溢出，默认只有63M，工程比较多时容易出现此问题

解决方案：在maven启动脚本（mvn.bat）中，重新设置堆大小（set MAVEN_OPTS= -Xms128m -Xmx512m）

 

问题2：maven install时出现此问题，日志如下：

原因分析：编译不通过，检查JDK版本

解决方案：使用正确的JDK版本，和开发时的一致
