Tried downloaded the tools-1.4.2.jar and run mvn install:install-file -DgroupId=com.sun -DartifactId=tools -Dversion=1.4.2 -Dpackaging=jar -Dfile=/path/to/file but it doesn't solve the problem.
尝试下载 tools-1.4.2.jar 并运行 mvn install:install-file -DgroupId=com.sun -DartifactId=tools -Dversion=1.4.2 -Dpackaging=jar -Dfile=/path/to/file 但它没有不解决问题。

Repoint your system environment parameter JAVA_HOME to JDK (1.5+) directory instead of JRE.
将您的系统环境参数 JAVA_HOME 重新指向 JDK (1.5+) 目录而不是 JRE。

According to Spring Source Roo and missing com.sun:tools:jar:1.4.2:
根据Spring Source Roo 和缺少的 com.sun:tools:jar:1.4.2：
If you are trying to get the latest version of SpringSource ROO working, with an x64 Java JDK, such as the latest JDK 1.6 update 20, there is unfortunately a missing tools.jar from the default
lib\directory of the JDK (tut tut tut Sun/Oracle). This will prevent Roo from working and therefore prevent Maven compilation. You would probably see an error similar to this: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.To correct this error, install an additional x86 JDK, repoint the JAVA_HOME and the PATH to the new JDK and restart the mvn process
如果您正在尝试使用 x64 Java JDK（例如最新的 JDK 1.6 update 20）使最新版本的 SpringSource ROO 正常工作，那么不幸的是，JDK 的默认
lib\目录中缺少一个 tools.jar （啧啧啧 Sun/甲骨文）。这将阻止 Roo 工作，从而阻止 Maven 编译。您可能会看到与此类似的错误：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，请安装额外的 x86 JDK，将 JAVA_HOME 和 PATH 重新指向新的 JDK 并重新启动 mvn 进程

i thought i had java_home set to jdk, but i guess in slackware both jre and jdk get installed in same folder. having both installed caused this problem. i uninstalled both, and reinstalled jdk (to be safe) and it fixed it.
我以为我将 java_home 设置为 jdk，但我猜在 slackware 中 jre 和 jdk 都安装在同一个文件夹中。两者都安装导致了这个问题。我卸载了两者，并重新安装了 jdk（为了安全）并修复了它。

Add this dependecy in pom.xml file.
在 pom.xml 文件中添加此依赖项。
in the <systemPath>property you have to write your JDK lib path.
在<systemPath>属性中，您必须编写 JDK lib 路径。
<dependency>
<groupId>com.sun</groupId>
<artifactId>tools</artifactId>
<version>1.4.2</version>
<scope>system</scope>
<systemPath>C:/Program Files/Java/jdk1.6.0_30/lib/tools.jar</systemPath>
</dependency>

I also had a similar issue and fixed int the following way.
我也遇到了类似的问题并通过以下方式修复了 int 。
Go to lib directory of JDK installed path in command prompt. Execute the below command to install to install tools.jar. $mvn install:install-file -DgroupId=sun.jdk -DartifactId=tools -Dpackaging=jar -Dversion=1.6 -Dfile=tools.jar
在命令提示符下转到 JDK 安装路径的 lib 目录。执行以下命令安装以安装tools.jar。$mvn install:install-file -DgroupId=sun.jdk -DartifactId=tools -Dpackaging=jar -Dversion=1.6 -Dfile=tools.jar
