当我在Roo中运行“执行日食”时，我得到了：

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]

      2) com.sun:tools:jar:1.4.2

1 required artifact is missing.

for artifact:

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但它没有解决问题。

运行ubuntu 10.04和maven 2.2

有什么建议吗？

Answer 1

将系统环境参数JAVA_HOME重新指向JDK（1.5+）目录而不是JRE。

Answer 2

根据Spring Source Roo and missing com.sun:tools:jar:1.4.2：

如果您正在尝试获取最新信息 SpringSource ROO的版本工作，用x64 Java JDK，比如最新的JDK 1.6更新20，有不幸的是，缺少tools.jar JDK的默认lib\目录（太，太太/甲骨文）。这将防止Roo工作，因此防止Maven编译。你会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，请安装额外的x86 JDK，重新命名 JAVA_HOME和PATH到新的JDK 并重新启动mvn进程

Answer 3

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。

Answer 4

在pom.xml文件中添加此依赖项。

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>

Answer 5

我也有类似的问题，并按以下方式修复。

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
