Could not find artifact com.sun:tools:jar:1.5.0

【maven package】，則依然報錯，但報的是另外一個錯誤：

[INFO] Scanning for projects…[INFO]

後在網上查找解決方法，有外國網友說，在pom.xml添加如下依賴即可：

<dependencies>

<dependency>

<groupId>com.sun</groupId>

<artifactId>tools</artifactId>

<version>1.5.0</version>

<scope>system</scope>

<systemPath>${java.home}/../lib/tools.jar</systemPath>

</dependency>

</dependencies>

不過，我試過還是不行，另一個外國網友說，把eclipse中的【Windows】-【Preferences】-【Java】-【Install JREs】改為JDK，而不用JRE，如下圖所示：

雖然我勾選了JDK，但還是報錯，看了錯誤，發現在 C:\Program Files\Java\jre1.6.0_01/../lib/tools.jar無法找到tools:jar，這讓我有點納悶了，明明已經選了使用JDK了，怎麼還去JRE那裡找呢，于是我把【Windows】-【Preferences】-【Java】-【Install JREs】中的JRE給remove掉，再次【maven package】就OK了。
