tomcat8 Maven插件 - 无法找到的rt.jar

Question

我想使用maven tomcat8插件，我下载来自：

https://mvnrepository.com/artifact/org.apache.tomcat.maven/tomcat8-maven-plugin

当我mvn tomcat8:run跑，我得到以下错误：

然而，rt.jar中确实存在，我的JAVA_HOME环境设置正确：

mvn -v Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T16:41:47+00:00)

Answer 1

问题是路径中的URL编码空格字符C:\Program%20Files\ ...

它不是 - afaik - 有效的Windows路径。

如果你没有明确地设置它，它可能是一个插件中的错误。

更新：这似乎是一个错误：

Maven goal of tomcat8:run fails if Java runtime is installed in path containing spaces
