JAVA_HOME和Maven依赖关系的怪异问题 [英] weird problem with JAVA_HOME and maven dependencies

问题描述

当我在项目上运行maven软件包时，我已将JAVA_HOME变量设置为C:\Program Files\Java\jre6\，它告诉我无法解决依赖关系

I have JAVA_HOME variable set to C:\Program Files\Java\jre6\ when I run maven package on the project it tells me that it can't resolve dependency

[ERROR] Failed to execute goal org.codehaus.mojo:aspectj-maven-plugin:1.0:compile (default) on project roo: Execution default of goal o
rg.codehaus.mojo:aspectj-maven-plugin:1.0:compile failed: Plugin org.codehaus.mojo:aspectj-maven-plugin:1.0 or one of its dependencies
could not be resolved: Could not find artifact com.sun:tools:jar:1.4.2 at specified path C:\Program Files\Java\jre6/../lib/tools.jar ->
[Help 1]

因此，它假设JAVA_HOME实际上比实际深度更深一层，我查看了maven本地存储库，发现log4j 1.2.16使用了这种依赖关系

so it assumes that JAVA_HOME is actually one level deeper than it actually is, I have looked through maven local repository and found that log4j 1.2.16 uses this dependency

我试图使JAVA_HOME看起来像C:\Program Files\Java\jre6\bin\，但是随后maven无法运行，它告诉我我的JAVA_HOME路径错误

I tried to make JAVA_HOME look like C:\Program Files\Java\jre6\bin\ but then maven wouldnt run, it told me that my JAVA_HOME path was wrong

推荐答案

您将需要Java JDK，而不仅仅是JRE.您可以在 Oracle的Java页面

You will need a Java JDK not just a JRE. You can get one at Oracle's Java Page

从 Maven属性指南:

${java.home} specifies the path to the current JRE_HOME environment use with relative paths to get for example:
<jvm>${java.home}../bin/java.exe</jvm>

例如，在c:\jdk中使用JDK，行家$ {java.home}指向c:\jdk\jre

And with a JDK for example in c:\jdk the maven ${java.home} is pointing to c:\jdk\jre
