[英]Maven: Cannot resolve property in pom.xml
I just started converting my Android Project into Maven. 我刚刚开始将我的Android项目转换为Maven。
I'm trying to use properties
in my pom.xml but I'm getting the error: 我正在尝试在pom.xml中使用properties
,但出现错误:
Dependency com.google.android:android${android.version} not found 找不到依赖项com.google.android:android${android.version}
I'm also getting the same errors for the other properties except for ${junit.version}
. 除了${junit.version}
之外,其他属性也遇到了相同的错误。
Below is my pom.xml : 以下是我的pom.xml :

It fetched the dependencies just fine for me. 它获取了对我来说很好的依赖项。 I suggest checking a few things: 我建议检查一些事情:
mvn -X compile
to get more information about which mirrors are being used 运行mvn -X compile
以获得有关正在使用哪些镜像的更多信息 settings.xml
to see which mirrors you are using 检查您的maven settings.xml
以查看您正在使用的镜像 I recommend to create a android maven project with androidKickstartR ( http://androidkickstartr.com/ ) and coppy the pom.xml to your own project where you can edit it to your needs. 我建议使用androidKickstartR( http://androidkickstartr.com/ )创建一个android maven项目,并将pom.xml复制到您自己的项目中,然后您可以根据需要对其进行编辑。
When ready build the project with: 准备好使用以下命令构建项目时:
mvn clean install android:deploy
