发布时忽略Android依赖项。

Question

在用gradle构建我的项目时，我会收到很多这样的警告。我看到了https://stackoverflow.com/a/15794650/864069，但我不清楚如何让这些人闭嘴。听起来，我所依赖的这些东西的任何版本都是为了支持在android.jar中打包的版本而被剥离掉的。

我想这没什么，但我真的想把这些关起来，这样我看到的东西才是真正的问题。

所以，我很好奇：

1. 这说明问题了吗？看来绝对不是。
2. 我该怎么闭嘴？
3. 不是每个人都看到这一组警告吗？我对使用gradle + android.Log的人是否看到了这组警告表示怀疑。

Answer 1

我不确定这会不会产生问题。最好的做法是遵循警告中的建议，或者完全排除依赖(您的第2点，我已经在下面回答了)。

我也看到了这些警告，特别是“共用日志”的警告。

您所链接的线程中的答案是，您应该忽略这些依赖项，因为Android已经包含了这些依赖项(我认为)。如果我错了，请纠正我。

例如，如果您特别需要公用日志记录(或提供类似警告的其他日志记录)，则将其从列表中删除。

build.gradle文件：

dependencies {
    ...
    compile 'commons-logging:commons-logging:1.1.3' #Remove this line; you don't need it.
    ....
}

另外，如果您有一个依赖项，需要将公用日志记录作为一个传递依赖项，那么也应该将它排除在外。

示例：

dependencies {
    ...
    compile 'some.package.that:requires_commons_logging:1.2.3'
    ....
}

变成了

dependencies {
    ...
    compile ('some.package.that:requires_commons_logging:1.2.3') {
        exclude group: 'commons-logging', module: 'commons-logging'
    }
    ....
}

完全排除它的一种简单方法也可以通过将其添加到build.gradle文件中来完成，而不必在每个依赖项中排除它：

configurations {
    all*.exclude group: 'commons-logging', module: 'commons-logging'
}

最后，要查看依赖树(并查看每个依赖项各自临时导入哪些可以冲突，非常有用)，请从项目的根中使用以下命令：

./gradlew :your_module_name:dependencies

Answer 2

如果要对警告保持沉默，则必须在build.gradle中为每个依赖项添加以下内容：

exclude group: 'org.apache.httpcomponents', module: 'httpclient'

它将是：

dependencies {
    ...
    compile ('some.package.that:requires_commons_logging:1.2.3') {
        exclude group: 'commons-logging', module: 'commons-logging'
    }
    ....
}
