com.sun：tools：jar：在roo中運行“perform eclipse”時缺少1.4.2

Question

當我在Roo中運行“執行日食”時，我得到：

roo> perform eclipse

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]

  Path to dependency: 
      1) org.codehaus.mojo:aspectj-maven-plugin:maven-plugin:1.0
      2) com.sun:tools:jar:1.4.2

----------
1 required artifact is missing.

for artifact: 
  org.codehaus.mojo:aspectj-maven-plugin:maven-plugin:1.0

嘗試下載工具-1.4.2.jar並運行mvn install：install-file -DgroupId = com.sun -DartifactId = tools -Dversion = 1.4.2 -Dpackaging = jar -Dfile = / path / to / file但它沒有解決問題。

運行ubuntu 10.04和maven 2.2

有什么建議？

Answer 1

將系統環境參數JAVA_HOME重新指向JDK（1.5+）目錄而不是JRE。

Answer 2

根據Spring Source Roo和缺少com.sun：tools：jar：1.4.2 ：

如果您正在嘗試使用x64 Java JDK（例如最新的JDK 1.6更新20）來運行最新版本的SpringSource ROO，那么遺憾的是JDK的默認lib\\目錄中缺少tools.jar（tut tut tut）太陽/ Oracle）的。 這將阻止Roo工作，從而阻止Maven編譯。 您可能會看到類似於此的錯誤：

 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. 

要更正此錯誤，請安裝其他x86 JDK，將JAVA_HOME和PATH重新指向新JDK並重新啟動mvn進程

Answer 3

我以為我把java_home設置為jdk，但我想在slackware中jre和jdk都安裝在同一個文件夾中。 兩個安裝都導致了這個問題。 我卸載了兩個，並重新安裝了jdk（為了安全）並修復了它。

Answer 4

在pom.xml文件中添加此依賴項。

在<systemPath>屬性中，您必須編寫JDK lib路徑。

    <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

我也有類似的問題，並通過以下方式修復。

在命令提示符下轉到JDK安裝路徑的lib目錄。 執行以下命令安裝以安裝tools.jar。 $ mvn install：install-file -DgroupId = sun.jdk -DartifactId = tools -Dpackaging = jar -Dversion = 1.6 -Dfile = tools.jar
