今天在使用maven打包项目时遇到一个错误：
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.4:compile (default-compile) on project zjydpt: Fatal error compiling: tools.jar not found: D:\Java\jre7..\lib\tools.jar -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch. [ERROR] Re-run Maven using the -X switch to enable full debug logging. [ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles: [ERROR] [Help 1] 我使用的是 C:\Users\Administrator>mvn -v Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 21:51: 28+0800) Maven home: D:\apache-maven-3.0.5-bin\apache-maven-3.0.5\bin.. Java version: 1.7.0_67, vendor: Oracle Corporation Java home: D:\Java\jdk1.7.0_67\jre Default locale: zh_CN, platform encoding: GBK OS name: “windows 7”, version: “6.1”, arch: “amd64”, family: “windows” 直接从eclipse里面打包会报错可以尝试使用: 1、在eclipse里面右键项目-run as-maven build-在弹出框Goals里面直接输入clean进行清理 ，然后输入package进行打包，不用加mvn前缀（PS：估计是maven版本问题吧！） 2、在硬盘里找到你的项目，然后按住shift右键选择‘在此处打开命令窗口’，然后输入mvn clean清理，再输入mvn package进行打包。我是使用第二种方法进行打包的，打包完成之后发现在eclipse里面重新打包居然可以了 ，很是神奇有木有！！！
