windows - Build.xml 给出问题。 ."CreateProcess error=87, The parameter is incorrect"

Question

我试图在 Windows 环境中使用 ant 构建脚本来执行我的 java 程序。

但是我遇到了以下问题。这是在linux环境中工作的。

Answer 1

似乎您的 CLASSPATH 太长，Windows 无法处理。

谷歌“CreateProcess error=87，参数不正确”。另见 answer .

您需要缩短类路径。尝试仅包含 StockQuoteClient 的实际依赖项，而不包含所有“*.jar”条目。
