com.sun：tools：jar：在roo中运行“perform eclipse”时缺少1.4.2
当我在Roo中运行“执行日食”时，我得到：

运行ubuntu 10.04和maven 2.2
有什么建议么？
将系统环境参数JAVA_HOME重新指向JDK（1.5+）目录而不是JRE。
根据Spring Source Roo和缺少的com.sun：tools：jar：1.4.2 ：
如果您正在尝试使用x64 Java JDK（例如最新的JDK 1.6更新20）来运行最新版本的SpringSource ROO，那么遗憾的是缺少来自JDK的默认
lib\目录的tools.jar（tut tut tut）太阳/ Oracle）的。 这将阻止Roo工作，从而阻止Maven编译。 你可能会看到类似这样的错误：Error message: Missing: ---------- 1) com.sun:tools:jar:1.4.2 Try downloading the file manually from the project website. Then, install it using the command: mvn install:install-file -DgroupId=com.sun -DartifactId=tools -Dversion=1.4.2 -Dpackaging=jar -Dfile=/path/to/file Alternatively, if you host your own repository you can deploy the file there: mvn deploy:deploy-file -DgroupId=com.sun -DartifactId=tools -Dversion=1.4.2 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id] ---------- 1 required artifact is missing.要更正此错误，请安装其他x86 JDK，将JAVA_HOME和PATH重新指向新JDK并重新启动mvn进程
我以为我把java_home设置为jdk，但我想在slackware中jre和jdk都安装在同一个文件夹中。 两个安装都导致了这个问题。 我卸载了两个，并重新安装了jdk（为了安全）并修复了它。
在pom.xml文件中添加此依赖项。
在
com.sun tools 1.4.2 system C:/Program Files/Java/jdk1.6.0_30/lib/tools.jar
我也有类似的问题，并通过以下方式修复。
在命令提示符下转到JDK安装路径的lib目录。 执行以下命令安装以安装tools.jar。 $ mvn install：install-file -DgroupId = sun.jdk -DartifactId = tools -Dpackaging = jar -Dversion = 1.6 -Dfile = tools.jar
