Must use JDK 1.5.x or higher to build Openfire

ant build openfire 是发生错误Must use JDK 1.5.x or higher to build Openfire

解决 ：修改build.xml 文件 找到文件

<condition property="java.not.ok" value="true">

<not>
<or>
<contains string="${ant.java.version}" substring="1.5"/>
<contains string="${ant.java.version}" substring="1.6"/>
</or>
</not>
</condition>
更改如下：
<condition property="java.not.ok" value="true">
<not>
<or>
<contains string="${ant.java.version}" substring="1.5"/>
<contains string="${ant.java.version}" substring="1.6"/>
<contains string="${ant.java.version}" substring="1.7"/>
</or>
</not>
</condition>
