我的Maven Config有什么问题? [英] What is wrong with my Maven Config?

问题描述

我想检出声纳，所以我在pom.xml中添加了以下代码段，依赖项部分取自

I want to checkout sonar, so I added the following snippet to my pom.xml the dependency part was taken from http://maven.apache.org/general.html#tools-jar-dependency

<profile>
     <id>sonar</id>
     <activation>
        <activeByDefault>true</activeByDefault>
     </activation>
     <properties>
       <sonar.jdbc.url>jdbc:derby://localhost:1527/sonar;create=true</sonar.jdbc.url>
       <sonar.jdbc.driverClassName>org.apache.derby.jdbc.ClientDriver
       </sonar.jdbc.driverClassName>
       <sonar.jdbc.username>sonar</sonar.jdbc.username>
       <sonar.jdbc.password>sonar</sonar.jdbc.password>
       <sonar.host.url>http://localhost:8080/sonar</sonar.host.url>
     </properties>
     <dependencies>
    <dependency>
    <groupId>com.sun</groupId>
    <artifactId>tools</artifactId>
    <version>1.4.2</version>
    <scope>system</scope>
    <systemPath>${java.home}/../lib/tools.jar</systemPath>
    </dependency>
      </dependencies>
</profile>

不幸的是，错误仍然存​​在

Unfortunatly the error persists

Embedded error: 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

我还遵循了将缺少的jar手动添加到存储库的建议，这没有任何效果.

I also followed the suggestion to add the missing jar manually to the repository, which had no effect.

mvn install:install-file -DgroupId=com.sun -DartifactId=tools -Dversion=1.4.2 -Dpackaging=jar -Dfile=$JAVA_HOME/lib/tools.jar

我在做什么错了?

我验证了tools.jar已添加到我的本地存储库中.在调试模式下，maven显示错误:

I verified that tools.jar has been added to my local repository. In debug mode maven shows the error:

1 required artifact is missing.

for artifact: 
  group:artifact:war:1.0.0-BUILD-SNAPSHOT

from the specified remote repositories:
  central (http://repo1.maven.org/maven2)

推荐答案

您是否在Eclipse中运行它?如果答案是肯定的，那么这将是一个令人烦恼且非常容易被误解的问题.在此处

Are you running this in eclipse? If the answer is yes, this is an annoying and very misunderstood problem. Take a look at my answer here

启动时，您可能没有将eclipse指向正确的jre/jdk(这不是您必须配置的东西，而是Windows)

You may not be pointing eclipse to the right jre/jdk when you're starting up (this is something you didn't necessarily configure rather was Windows)
