I am getting the above error when trying through aliyun cli. What modification should i perform.

如题，能介绍下这个项目是做什么的吗，解决什么问题，具体怎么使用的？

https://github.com/eclipse-vertx/vert.x

Currently, If the user has two options like:

    @Option(shortName = "e", longName = "exception", flag = true)
    @Description("Watch after throw exception")
    public void setException(boolean exception) {
        isException = exception;
    }
    @Option(shortName = "E", longName = "regex", flag = true)
    @Description("Enable regular expression to match (wildcard matching by default)")
    public void setRegEx(boolean regEx) {
        isRegEx = regEx;
    }

No matter -e/-E, only isException is true.

这个配置

Option(longName = "acceptValueBoolean", flag = true, acceptValue = true)

应该是允许设置 --acceptValueBoolean=false 这样子的形式的，但是实际上跑时，会抛出异常：

Exception in thread "main" com.taobao.middleware.cli.InvalidValueException: The value 'false' is not accepted by 'acceptValueBoolean'
	at com.taobao.middleware.cli.impl.DefaultParser.handleLongOptionWithEqual(DefaultParser.java:392)
	at com.taobao.middleware.cli.impl.DefaultParser.handleLongOption(DefaultParser.java:337)
	at com.taobao.middleware.cli.impl.DefaultParser.visit(DefaultParser.java:235)
	at com.taobao.middleware.cli.impl.DefaultParser.parse(DefaultParser.java:133)
	at com.taobao.middleware.cli.impl.DefaultCLI.parse(DefaultCLI.java:70)
	at com.taobao.arthas.core.shell.command.internal.GrepHandler.main(GrepHandler.java:129)

原因是 .setFlag(option.flag()) 的实现里会设置 SingleValued 值 。

所以要把 .setSingleValued(option.acceptValue())放在后面。
