tomcat8 maven插件 - 找不到rt.jar

Question

我正在尝试使用我从以下网站下载的maven tomcat8插件：

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

当我使用mvn tomcat8:run运行时，我收到以下错误：

但是，rt.jar确实存在并且我的JAVA_HOME环境设置正确：

mvn -v Apache Maven 3.3.9（bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T16：41：47 + 00:00） Maven home：C：\ Users \ Jonathan \ Downloads \ apache-maven-3.3.9-bin \ apache-maven-3.3.9 Java版本：1.8.0_151，供应商：Oracle Corporation Java home：C：\ Program Files \ Java \ jdk1.8.0_151 \ jre 默认语言环境：en_GB，平台编码：Cp1252 操作系统名称：“windows 10”，版本：“10.0”，arch：“amd64”，系列：“dos”

Answer 1

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

它不是 - afaik - 有效的Windows路径。

如果您没有自己明确设置它可能是插件中的错误。

更新：它似乎是一个错误：

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

Answer 2

tomcat maven插件支持的最高版本是tomcat 7，你可以试试有几个嵌入式容器的spring boot
