Question

我们正在尝试使用com.google.android.gms:play-services-location，但无法构建我们的项目。问题似乎是maven尝试下载JAR，而此工件以AAR文件的形式存在。这是我们的pom.xml

<dependency>
      <groupId>com.google.android.gms</groupId>
      <artifactId>play-services-location</artifactId>
      <version>17.0.0</version>
    </dependency>
...
<repositories>
    <repository>
      <id>google-local-repo</id>
      <name>Google Maven Repo</name>
      <url>file:///Users/sjain68/Library/Android/sdk/extras/google/m2repository</url>
    </repository>
    <repository>
      <id>google-remote-repo</id>
      <name>Google Maven Repo</name>
      <url>https://maven.google.com</url>
    </repository>
  </repositories>

无论我们怎么努力，都会遇到此错误：

[ERROR] Failed to execute goal on project android: Could not resolve dependencies for project com.google.zxing:android:apk:4.7.10: Failure to find com.google.android.gms:play-services-location:jar:17.0.0 in https://maven.google.com was cached in the local repository, resolution will not be reattempted until the update interval of google-remote-repo has elapsed or updates are forced -> [Help 1]

，这是事实。 JAR不存在。它是一个AAR文件。我们如何告诉Maven寻找AAR文件而不是JAR文件？

Answer 1

使用<type>aar</type>使它工作：

<dependency>
      <groupId>com.google.android.gms</groupId>
      <artifactId>play-services-location</artifactId>
      <version>17.0.0</version>
      <type>aar</type>
    </dependency>

Maven：找不到com.google.android.gms：play-services-location：jar
