how to escape '&' in maven pom property values
提问by dermoritz
I need to set a URL via a maven property (to be replaced per profile). The problem is that this URL contains some &and maven doesn't like this (if URL contains &_program):
我需要通过 Maven 属性设置 URL（按配置文件替换）。问题是这个 URL 包含一些&而 maven 不喜欢这个（如果 URL 包含 &_program）：
"The reference to entity "_program" must end with the ';' delimiter." error occurs in pom on this line.
“对实体“_program”的引用必须以';'结尾 分隔符。” 在这一行的 pom 中发生错误。
So how to escape this character or how to escape a hole line that might contain some "special" characters. (What other characters are forbidden in property-values?)
那么如何转义这个字符或如何转义可能包含一些“特殊”字符的孔线。（属性值中禁止使用哪些其他字符？）

I've not used maven but from the sounds of it, standard XML escaping would get the job done. In your case you can try using
我没有使用过 maven，但从它的声音来看，标准的 XML 转义可以完成工作。在您的情况下，您可以尝试使用
&instead of &
&代替 &

You can escape one character or a whole line that might contain some "special" characters by surrounding property value with <![CDATA[ property value ]]>. For example for some URL it would look like:
您可以通过将属性值括在<![CDATA[ property value ]]>. 例如，对于某些 URL，它看起来像：
<properties>
<some.url><![CDATA[http://stackoverflow.com?param_1=1¶m_2=2]]></some.url>
</properties>
