Question

从命令行运行jhipster时出现以下错误，我在Windows机器上使用jhipster最新版本（v3.12.2）。 gradle build似乎存在问题。

gradlew.bat bootRun

是的，此版本存在一个gradle问题，如果gradle缓存路径包含空格，则会产生此错误。我建议您将gradle缓存永久删除到没有空格的路径：Set Gradle Cache Directory?

如果您需要像我一样的临时快速修复，您可以使用脏方法修补此修复JHipster类路径。假设您的Windows用户名是“您的名字”。然后它将成为路径字符串的一部分，你将需要用“你的〜1”替换它（它是8个字符等效的Windows长名称目录，即目录名称的前6个字符小写，没有空格+“ 〜1" ）。您可以在build.gradle第55行修补它，问题就消失了：

        attributes 'Class-Path': configurations.runtime.files.collect {
            it.toURL().toString().replaceFirst(/file:\/+/, '/').replace("Your Name", "yourna~1")
        }.join(' ')
