我正在尝试编译一个使用 ejabberd 的新 xmpp 库的模块。

我有一个非常简单的rebar.config文件：

{deps, [
    {xmpp, ".*", {git, "https://github.com/processone/xmpp", {tag, "1.1.4"}}}
]}.

当我尝试运行rebar3 eunit或rebar3 compile收到错误消息时：

$ rebar3 compile

但是，当我单独编译这个模块时，它可以工作：

我怎样才能知道发生了什么？是rebar.config.scriptxmpp 库的错吗？

事实证明，xmpp无法使用开箱即用的 rebar3 进行编译。我在 GitHub 上打开了一个问题。

作为一种解决方法，将以下内容添加到我的rebar.config文件中有效：

{overrides, [
    {add, xmpp, [{erl_opts, [{i, "_build/default/lib/fast_xml/include"}]}]}
]}.
