Android：Maven 最终存档名称

Question

在 maven mvn clean install 运行结束时，创建的工件由 maven-install-plugin 自动安装到存储库中：

[INFO] --- maven-install-plugin:2.3.1:install (default-install) @ project ---
[INFO] Installing C:\Users\mannaz\workspace\project\target\project-0.1.1-test.apk to C:\Users\mannaz\.m2\repository\at\mannaz\android\project\0.1.1\project-0.1.1.apk
[INFO] Installing C:\Users\mannaz\workspace\project\pom.xml to C:\Users\mannaz\.m2\repository\at\mannaz\android\project\0.1.1\project-0.1.1.pom
[INFO] Installing C:\Users\mannaz\workspace\project\target\project-0.1.1-test.jar to C:\Users\mannaz\.m2\repository\at\mannaz\android\project\0.1.1\project-0.1.1.jar

不幸的是，最终的 apk 文件名在此过程中被重命名（project-0.1.1-test.apk>>project-0.1.1.apk）。

最初apk文件的名称是通过

<finalName>${project.artifactId}-${project.version}-${webservice.target}</finalName>

如何在构建存档中指定 apk 文件的最终名称而不覆盖 <version/> 属性本身？

原因：

运行mvn clean install -X导致Maven在build life cycle末尾执行default-install目标，它使用默认的groupId：artifactId：packaging：version安装生成的apk（我使用abc-123作为最终名称示例）：

[INFO] --- maven-install-plugin:2.1:install (default-install) @ myapp ---
[DEBUG] Configuring mojo org.apache.maven.plugins:maven-install-plugin:2.1:install from plugin realm ClassRealm[plugin>org.apache.maven.plugins:maven-install-plugin:2.1, parent: sun.misc.Launcher$AppClassLoader@11b86e7]
[DEBUG] Configuring mojo 'org.apache.maven.plugins:maven-install-plugin:2.1:install' with basic configurator -->
[DEBUG]   (f) artifact = com.mycompany:myapp:apk:1.2.2-SNAPSHOT
[DEBUG]   (f) attachedArtifacts = [com.mycompany:myapp:jar:1.2.2-SNAPSHOT]
[DEBUG]   ... ...
[DEBUG] -- end configuration --
[INFO] Installing C:\workspace\myapp\target\abc-123.apk to c:\maven\repository\com\mycompany\myapp\1.2.2-SNAPSHOT\myapp-1.2.2-SNAPSHOT.apk
[INFO] ... ...

解决方案：

此默认工件安装 AFAIK 既无法避免也无法修改，并且在默认安装目标执行期间，<finalName> 不会对目标文件名（使用固定模式 artifactId-version-classifier.packaging）产生任何影响。解决方案是在构建生命周期中附加额外的工件，取决于您的需求（如果您只需要在myapp-1.2.2-SNAPSHOT 后面添加一些后缀），最简单的方法是在 android-maven-plugin 配置中定义一个classifier：

<plugin>
  <groupId>com.jayway.maven.plugins.android.generation2</groupId>
  <artifactId>android-maven-plugin</artifactId>
  <extensions>true</extensions>
  <configuration>
    <classifier>test</classifier>
    ... ...
  </configuration>
</plugin>

这将导致 myapp-1.2.2-SNAPSHOT.apk 和 myapp-1.2.2-SNAPSHOT-test.apk 都安装到 maven 存储库中：

[INFO] --- maven-install-plugin:2.1:install (default-install) @ myapp ---
[DEBUG] Configuring mojo org.apache.maven.plugins:maven-install-plugin:2.1:install from plugin realm ClassRealm[plugin>org.apache.maven.plugins:maven-install-plugin:2.1, parent: sun.misc.Launcher$AppClassLoader@11b86e7]

[DEBUG]   (f) attachedArtifacts = [com.mycompany:myapp:jar:1.2.2-SNAPSHOT, com.mycompany:myapp:apk:test:1.2.2-SNAPSHOT]
[DEBUG]   ... ...
[DEBUG] -- end configuration --
[INFO] Installing C:\workspace\myapp\target\abc-123.jar to c:\maven\repository\com\mycompany\myapp\1.2.2-SNAPSHOT\myapp-1.2.2-SNAPSHOT.apk
