if-statement - NAnt:无法解析为 bool 值

Question

<if test="${deployErrors} &gt; 0">
   <fail message="MSDeploy failed" />
</if>

${deployErrors}由正则表达式捕获组填充，并且具有数值或空字符串。如何在 NAnt if 块中检查这是否大于 0？如果部署错误包含“1”，这是我得到的错误

'1 > 0' is not a valid value for attribute 'test' of . Cannot resolve '1 > 0' to boolean value. String was not recognized as a valid Boolean.

Answer 1

我没试过，但我认为你需要在花括号内表达你的整个表达:

<if test="${deployErrors > 0}">

See also the second example in the documentation page.

这有效:

<if test="${deployErrors != ''}">
