Build promotion: how do you manage dependencies?

I am trying to understand all the implications of switching our java projects from a Snaphot/Release policy to build promotion. One obvious step is that each build ends up creating an artifact that might be going all the way to the production environment, so there's not Snapshot anymore. But then, how should I manage the link from a project to other artifacts, that may or may not be allowe

建立促销:你如何管理依赖关系?

我试图理解从Snaphot / Release策略切换我们的java项目以构建推广的所有含义。 一个显而易见的步骤是,每个构建最终创建一个可能一直到生产环境的构件,所以不再有Snapshot。 但是,那么,我应该如何管理从项目到其他工件的链接,这些工件可能会或可能不被允许进行生产? 我很难在这个特定主题上找到有价值的信息。 当然,建立促进被谈论了很多,但是依靠迁移来建立促进的依赖管理具有较低的可见性。 我看到两个选择:

Nested generic with type bound results in compile error

Why does this result in a compile error: Optional<Optional<Integer>> a = Optional.of(Optional.of(1)); Optional<Optional<? extends Number>> b = a; whereas the following does not?: Optional<Optional<Integer>> a = Optional.of(Optional.of(1)); Optional<Optional<? extends Number>> c = a.map(x->x); Although Optional<Integer> is a sybtype of O

与类型绑定的嵌套泛型导致编译错误

为什么会导致编译错误: Optional<Optional<Integer>> a = Optional.of(Optional.of(1)); Optional<Optional<? extends Number>> b = a; 而以下不? Optional<Optional<Integer>> a = Optional.of(Optional.of(1)); Optional<Optional<? extends Number>> c = a.map(x->x); 尽管Optional<Integer>是Optional<? extends Number>的sybtype Optional<? exte

Sending binary data with HttpURLConnection

i want to use google speech api, i've found this https://github.com/gillesdemey/google-speech-v2/ where everything is explained well, but and im trying to rewrite it into java.

Twitter Android SDK not executing Callback

I'm running this code with a Twitter handle I'm pretty sure doesn't exist in order to test error handling. The breakpoints on the Callback are never hit, neither for success nor failure. Any pointers on why this is? Just as a note, this code works fine with a valid Twitter handle, but doesn't call the Callback either. final Callback<Tweet> actionCallback = new Callback

Twitter Android SDK不执行回叫

我正在用一个Twitter句柄运行这个代码,我相当肯定不存在为了测试错误处理。 回调中的断点不会被触及,既不会成功也不会失败。 任何指针为什么这是? 就像注意一样,这段代码对于有效的Twitter句柄工作正常,但不会调用回调函数。 final Callback<Tweet> actionCallback = new Callback<Tweet>() { @Override public void success(Result<Tweet> result) { int x = 1; x++; // T
