Mac os 编码识别错误

来源：互联网发布：qq语音网络连接不稳定编辑：程序博客网时间：2024/06/15 23:11

起因：在Mac 上编写java 程序，用maven进行管理，执行mvn compile, 编译失败但提示的错误是乱码

原因：JDK对mac os 的默认编码识别错误，而maven使用java相关命令编译，打印编译错误，因此打印的错误无法正常显示

可以安装JDK1.8 来解决此问题，并设置JAVA_HOME 来解决此问题

在~/.bashrc 中加入

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home

对比一下

mac@xxxx:/Library/Java$ mvn -vApache Maven 3.2.3 (33f8c3e1027c3ddde99d3cdebad2656a31e8fdf4; 2014-08-12T04:58:10+08:00)Maven home: /usr/local/apache-maven-3.2.3Java version: 1.6.0_65, vendor: Apple Inc.Java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/HomeDefault locale: zh_CN, platform encoding: EUC_CNOS name: "mac os x", version: "10.9.4", arch: "x86_64", family: "mac"mac@xxxx:/Library/Java$ source ~/.bashrc------------- hello -----------mac@xxxx:/Library/Java$ mvn -vApache Maven 3.2.3 (33f8c3e1027c3ddde99d3cdebad2656a31e8fdf4; 2014-08-12T04:58:10+08:00)Maven home: /usr/local/apache-maven-3.2.3Java version: 1.8.0_11, vendor: Oracle CorporationJava home: /Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home/jreDefault locale: zh_CN, platform encoding: UTF-8OS name: "mac os x", version: "10.9.4", arch: "x86_64", family: "mac"

在没有指定JAVA_HOME 前，mvn 识别的java version 是1.6, 平台编码是 EUC_CN(gb2312) ，安装JDK 1.8 并设置JAVA_HOME 以后，mvn 识别的java version 是1.8, 平台编码是 UTF-8

PS: Mac 上到处都是坑，程序员最适合的开发环境还是Ubuntu
