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]

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.

Running ubuntu 10.04 and maven 2.2

Any suggestions?

回答1:

Repoint your system environment parameter JAVA_HOME to JDK (1.5+) directory instead of JRE.

回答2:

According to Spring Source Roo and missing 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

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.

回答4:

Add this dependecy in pom.xml file.

in the <systemPath> property you have to write your JDK lib path.

    <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>

回答5:

I also had a similar issue and fixed int the following way.

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
