使用 Eclipse/Maven 构建 Hadoop - 缺少工件 jdk.tools:jdk.tools:jar:1.6 [英] Buiding Hadoop with Eclipse / Maven - Missing artifact jdk.tools:jdk.tools:jar:1.6

问题描述

我正在尝试导入 cloudera 的 org.apache.hadoop:hadoop-client:2.0.0-cdh4.0.0 from cdh4 maven repo in a maven project in eclipse 3.81, m2e plugin, with oracle's jdk 1.7.0_05 on win7 using

I am trying to import cloudera's org.apache.hadoop:hadoop-client:2.0.0-cdh4.0.0 from cdh4 maven repo in a maven project in eclipse 3.81, m2e plugin, with oracle's jdk 1.7.0_05 on win7 using

<dependency>
    <groupId>org.apache.hadoop</groupId>
    <artifactId>hadoop-client</artifactId>
    <version>2.0.0-cdh4.0.0</version>
</dependency>

但是，我收到以下错误:

however, I get the following error:

The container 'Maven Dependencies' references non existing library 'C:UsersMyUserId.m2
epositoryjdk	oolsjdk.tools1.6jdk.tools-1.6.jar'

更具体地说，maven 声明缺少以下工件

more specific, maven states that the following artifact is missing

Missing artifact jdk.tools:jdk.tools:jar:1.6

如何解决这个问题?

推荐答案

jdk.tools:jdk.tools(或 com.sun:tools，或任何你命名的it) 是一个与 JDK 一起分发的 JAR 文件.通常你将它添加到 Maven 项目中，如下所示:

jdk.tools:jdk.tools (or com.sun:tools, or whatever you name it) is a JAR file that is distributed with JDK. Usually you add it to maven projects like this:

<dependency>
    <groupId>jdk.tools</groupId>
    <artifactId>jdk.tools</artifactId>
    <scope>system</scope>
    <systemPath>${java.home}/../lib/tools.jar</systemPath>
</dependency>

请参阅 Maven 常见问题解答，用于将依赖项添加到 tools.jar

或者，您可以使用以下方法在本地存储库中手动安装 tools.jar:

Or, you can manually install tools.jar in the local repository using:

mvn install:install-file -DgroupId=jdk.tools -DartifactId=jdk.tools -Dpackaging=jar -Dversion=1.6 -Dfile=tools.jar -DgeneratePom=true

然后像 Cloudera 一样引用它，使用:

and then reference it like Cloudera did, using:

<dependency>
    <groupId>jdk.tools</groupId>
    <artifactId>jdk.tools</artifactId>
    <version>1.6</version>
</dependency>
