带有Gmail的Java电子邮件在Eclipse/Maven中与在打包的jar中表现不同

我有一个基于javax.mail的“Gmail.java”类，它通过Gmail帐户发送电子邮件已经有一段时间了

最近，我发现了Maven，并开始使用它来启动我所有的新项目

在这个最新的项目上（使用Maven原型），出于某种原因，无论我想在Eclipse中还是从部署的jar中运行程序，都需要打开或关闭以下属性：

props.put("mail.smtp.starttls.enable", "true");

如果在Eclipse内部运行时出现这一行，则会出现StackOverflow问题中经常提到的“PKIX路径构建失败”异常。然后，如果我打包我的应用程序并从某个linux shell运行它，一切都会好起来，电子邮件也会发送

另一方面，如果我对该行进行注释，则在Eclipse中运行时会发送电子邮件，如果我打包并部署，则会收到一个运行时错误，即与Gmail通信需要SSL

这是我的pom.xml，我想原因可能在那里
