我正在使用由以下命令启动的服务器。
mvn jetty:run 我想停止服务器，但我没有运行mvndocker：停止，甚至faild运行java -version，为什么？
[mirror@home wpse]$ mvn jetty:stop ///////////// Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. [mirror@home wpse]$ java ////////////// Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. [mirror@home wpse]$ java -version /////////////// Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine.
事实是，我仍然有大约50M的空闲内存，为什么我没有运行java -version？ java -version命令需要多less内存？
Mem: 1048800k total, 993728k used, 55072k free, 0k buffers Swap: 0k total, 0k used, 0k free, 0k cached
问题是使用maven创buildjvm时，jvm堆的默认大小是多less？
如何使Java使用Maven时使用较小的堆？
