【问题描述】：
我已经从 https://github.com/osmdroid/osmdroid 而且我无法构建它。我专注于存储库中的 OpenStreetMapViewer 项目。
我认为问题的根源在于我无法使用 maven，因为我在防火墙后面。对于我创建或克隆的所有 Android Studio 项目，我必须通过删除来修改 build.gradle
mavenCentral 而是使用：
jcenter {
url "http://jcenter.bintray.com/"
}
对于这个项目，build.gradle 将此行包含在 dependencies 块中：
dependencies {
compile 'com.android.support:appcompat-v4:22.2.+'
compile 'org.osmdroid:osmdroid-android:4.3'
compile 'org.osmdroid:osmdroid-third-party:4.3'
}
但是，在这里浏览 jcenter： https://bintray.com/bintray/jcenter 我没有看到 v4，只有 v7 (android-support-v7-appcompat)
我尝试将 v7 作为依赖项：
compile 'com.android.support:appcompat-v7:23.0.1'
这需要将 compileskdversion 更改为 23。
这样做我得到这个构建错误：
Error:A problem occurred configuring root project 'OpenStreetMapViewer'.
> Could not resolve all dependencies for configuration ':_debugCompile'.
> Could not resolve android.support:compatibility-v4:21.0.3.
Required by:

> peer not authenticated
看来 osmdroid 确实需要 v4，而不是 v7
在 Android SDK 管理器中，我安装了 Extras > Android Support Repository 22 和 > Android Support Library 23.0.1
我能做什么？
编辑 -------------------------------------------------------
我想我应该以尝试在不修改任何 build.gradle 或清单的情况下导入项目时发生的错误开始这个问题。关键是“How to Maven”的说明在这种情况下不起作用。

如前所述，我从这里克隆了 osmdroid：
https://github.com/osmdroid/osmdroid
我将系统环境变量 M2_HOME 设置为克隆的 osmdroid 项目的位置。
在settings.xml中：
<localRepository>D:\Users\myusername\AndroidstudioProjects\maven-android-sdk-deployer</localRepository>
我从这里下载了maven：
http://maven.apache.org/download.cgi
解压后的 D:\Program Files\apache-maven-3.3.3\bin，然后我也将其包含在 path 系统变量中。
在 DOS 窗口中，我转到 M2_HOME 并执行以下命令：
mvn 安装
我收到此错误：

在D:\Program Files\apache-maven-3.3.3\conf/settings.xml，我补充说：
<localRepository>D:\Users\myusername\AndroidstudioProjects\maven-android-sdk-deployer</localRepository>
这没有任何区别。这样做是否正确？
编辑 4 --------------------------------------------- --------------- 尝试将参数添加到证书的命令中：
mvn install -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true -Dmaven.wagon.http.ssl.ignore.validity.dates=true

以上所有可能都是必要的，但还不够。它的工作原理是让网络人员为 maven 的防火墙添加一个例外并添加 Sun Certs。

将 M2_HOME 设置为 maven 的位置，例如：
C:\Program 文件 (x86)\apache-maven-3.3.9\
将 mvn 命令的位置添加到系统变量中的路径：
C:\Program Files (x86)\apache-maven-3.3.9\bin
