Java 尝试运行mvn exec并在插件上获取mojo异常

所以我在跑步

mvn exec:java -Dexec.mainClass=”com.utm.csc.HTMLParser” -Dexec.args=”http://www.simplehtmlguide.com”

对于我的Java项目。它在Eclipse中运行，但使用上面的命令，会出现以下错误：

2012年年中，我在64位MacBook Air上使用OS X El Capitan。我做错了什么？

别忘了先编译<默认情况下，code>exec:java不会这样做

mvn clean compile exec:java -Dexec.mainClass=”com.utm.csc.HTMLParser” -Dexec.args=”http://www.simplehtmlguide.com”

---

错误在于你给出的论点不正确。您的命令应该是：

mvn clean compile exec:java-Dexec.mainClass=com.utm.csc.HTMLParser-Dexec.args=http://www.simplehtmlguide.com

请注意缺少引号。这可以从错误消息中得到提示：

java.lang.ClassNotFoundException:

“com.utm.csc.HTMLParser”

这意味着Java不知何故搜索了一个名为

“com.utm.csc.HTMLParser”

的类，但没有找到任何类，因为它实际上名为

com.utm.csc.HTMLParser

，没有引号
