我想把JDK tools.jar作为编译依赖项.我找到了一些示例,表明要使用systemPath属性,如下所示:

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

问题是Mac OS X的路径不正确(但对Windows和Linux来说是正确的).对于它,正确的路径是$ {java.home} /../ Classes/classes.jar.

我正在寻找一种方法来定义maven属性,这样如果系统被检测为Mac Os X,则值设置为$ {java.home} /../ Classes/classes.jar,否则设置为$ {java.home} /../ lib/tools.jar(就像可以用ANT一样).有人有想法吗？

当我跑步时mvn -version,我注意到了java_home要点...jdk\jre(如下图所示).那是错的吗？是不是应该指向...\jdk.x.y.z(没有\jre)？如果是这样,我该如何重置它？(在全局%java_home%指向jdk目录)

我在我的web项目中使用maven这是我的pom.xml看起来如何使用eclipse juno,使用apache tomcat 7,我运行windows xp OS,"C:\ Program Files\Java\jdk1.6.0_23\lib"是在我的工具罐子is.i试图在pom.xml中硬编码,但它在告诉着硬code.tried下面的使用配置文件仍然同样的错误"缺少神器的com.sun:工具:罐子:1.5.0"请请帮助我自谷歌搜索1周以来一直受够了

我试图构建PlayN示例项目:

Missing artifact com.sun:tools:jar:1.6  pom.xml /playn-cute line 6  Maven Dependency Problem

在每个pom.xml文件上.我该如何解决？

编辑:

我已将配置文件节点添加到pom.xml,但错误仍然存​​在.我已经检查过tools.jar它确实存在,而它没有.所以我已经添加tools.jar到lib文件夹了.仍然存在错误.

完整的pom.xml:
