aliyun的maven怎么配置不到eclipse

 虽然有一种方法可以使用模板并通过引用传递C数组，但我不确定这是否是您真正想要的： 示例 
 
 在C ++ 11中，我更喜欢使用std::intializer_list来使调用foo("c", {"a", "b", "c"})按预期工作： 
 
#include <initializer_list>

bool foo(const char* arg, std::initializer_list<const char*> strings) {
    for (const char* str : strings) {
        /* ... */
    }
}
 
 虽然我们在这里，你应该考虑使用C ++的字符串工具而不是从C继承的字符串工具： 
 
#include <initializer_list>
#include <string>

bool foo(const std::string& arg, std::initializer_list<std::string> strings) {
    for (const auto& str : strings) {
        if (arg == str) {
            return true;
        }
    }
    return false;
}
 
 请注意， std::initializer_list不拥有它提供访问的值，因此如果要存储它，请使用适当的容器，如std::vector 。 
 
 另外，如果你想要检查str是否存在arg ，为什么不使用std::find ？ 
 
#include <algorithm>
#include <initializer_list>
#include <string>

bool foo(const std::string& arg, std::initializer_list<std::string> strings) {
    return std::find(strings.begin(), strings.end(), arg) != strings.end();
}

While there is a way to make that work using templates and passing C-arrays by reference, I'm not sure if that is what you really want: example
 
In C++11 I'd much prefer to use a std::intializer_list to make the call foo("c", {"a", "b", "c"}) work as intended:
 
#include <initializer_list>

bool foo(const char* arg, std::initializer_list<const char*> strings) {
    for (const char* str : strings) {
        /* ... */
    }
}
 
While we're at it, you should consider using C++'s string facilities over those inherited from C:
 
#include <initializer_list>
#include <string>

bool foo(const std::string& arg, std::initializer_list<std::string> strings) {
    for (const auto& str : strings) {
        if (arg == str) {
            return true;
        }
    }
    return false;
}
 
Note that a std::initializer_list does not own the values it provides access to, so if you want to store it, use a proper container like std::vector instead.
 
Also, if checking for the presence of arg in str is all you want to do, why not use std::find?
 
#include <algorithm>
#include <initializer_list>
#include <string>

bool foo(const std::string& arg, std::initializer_list<std::string> strings) {
    return std::find(strings.begin(), strings.end(), arg) != strings.end();
}
