可能原因:
1.pom.xml中的java版本过高,跟服务器不匹配
mvn命令打包出现Execution exception: Java heap space问题
在maven/bin/mvn文件中设置

本文介绍了在Maven构建项目时遇到的两个常见问题:一是由于依赖库版本过高导致的编译失败,例如com.github.benmanes.caffeine;二是执行maven-compiler-plugin时遇到的'Java heap space'内存不足错误。解决方案包括降低依赖库版本和调整Maven的内存配置。对于依赖问题,可以尝试回退到兼容的版本;对于内存问题,需要修改Maven配置文件增加堆内存分配。
