Maven和机器人 - 稍有不同建立不同的环境 [英] Maven and android - Slightly different builds for different environments

问题描述

好吧我从蚂蚁切换到Maven在Android项目，并想知道如果它下面会很容易实现：

Ok I am switching from ant to maven on an android project and wondering if it the following would be easy to implement:

目前我有一个自定义的build.xml脚本，其中包含用于创建发布版本的几个目标。他们每个人都被用于构建应用程序来对不同的服务器的URL，而服务器可以是开发，生产，升级，甚至部署服务器，我们在其他国家运行。

Currently I have a custom build.xml script which has several targets for creating release builds. Each of them is used to build the application to run against a different server URL, where the server can be a dev, production, staging, or even deployment servers we have in other countries.

原因是，我们的应用程序将运行对几种不同的服务器取决于谁得到它，我不希望用户选择的是什么东西。相反，它应该很难codeD到应用程序，它是如何工作的目前。

The reason is that our application will run against several different servers depending who gets it, and I don't want that to be something the user chooses. Instead it should be hardcoded into the application, which is how it works currently.

这是很容易设置的蚂蚁，我只取值从[ENV]属性文件，然后替换在RES /价值/ config.xml中SERVER_URL字符串。例如：

This is fairly easy to setup in ant, I just take the values from the [env].properties file, and then replace out server_url string in res/values/config.xml. For instance:

ant release-prod

会拉读取名为prod.properties一个文件，该文件定义了什么是SERVER_URL了。我存储在配置/ config.xml中的config.xml文件是这样：

Would pull read a file named prod.properties which defines what the server_url was. I store the config.xml file in config/config.xml as so:

<?xml version="1.0" encoding="UTF-8"?>
<resources>
    <string name="config_server_url">@CONFIG.SERVER_URL@</string>
</resources>

然后我的ant脚本做到这一点：

Then my ant script does this:

<copy file="config/config.xml" todir="res/values" overwrite="true" encoding="utf-8">
    <filterset>
           <filter token="CONFIG.SERVER_URL" value="${config.server_url}" />
    </filterset>
</copy>

在哪里config.server_url于prod.properties定义。

Where config.server_url was defined in prod.properties.

我不知道我怎么可能做到与Maven类似的东西？有任何想法吗。我抬起头怎么读与Maven的属性文件，它看上去像结果是混合是否将工作或没有。

I'm wondering how I could accomplish something similar with Maven? Any ideas. I looked up how to read property files with maven and it looked like the results were mixed whether that would work or not.

推荐答案

在Maven的，这就是所谓的资源筛选，Android的Maven的插件支持过滤以下资源类型：

In Maven, this is called resource filtering, android-maven-plugin support filtering the following resource types:

• 在AndroidManifest.xml中，<一个href="http://stackoverflow.com/questions/10803088/how-do-i-change-my-androidmanifest-as-its-being-packaged-by-maven/10808077#10808077">see这个答案。
• 在资产/，请参阅<一href="http://stackoverflow.com/questions/10900017/android-maven-plugin-and-resource-filtering/10909923#10909923">this回答。
• RES /，见下文。

• AndroidManifest.xml, see this answer.
• assets/, see this answer.
• res/, see below.

样品水库/价值/ config.xml文件：

Sample res/value/config.xml:

<?xml version="1.0" encoding="UTF-8"?>
<resources>
  <string name="config_server_url">${config.server.url}</string>
</resources>

用于过滤下的资源的所有XML文件

样品POM配置/目录：

Sample pom configuration for filtering all xml file under res/ directory:

<build>
  <resources>
    <resource>
      <directory>${project.basedir}/res</directory>
      <filtering>true</filtering>
      <targetPath>${project.build.directory}/filtered-res</targetPath>
      <includes>
        <include>**/*.xml</include>
      </includes>
    </resource>
  </resources>
  <plugins>
    <plugin>
      <artifactId>maven-resources-plugin</artifactId>
      <executions>
        <execution>
          <phase>initialize</phase>
          <goals>
            <goal>resources</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
    <plugin>
      <groupId>com.jayway.maven.plugins.android.generation2</groupId>
      <artifactId>android-maven-plugin</artifactId>
      <extensions>true</extensions>
      <configuration>
        <sdk>
          <platform>10</platform>
        </sdk>
        <undeployBeforeDeploy>true</undeployBeforeDeploy>
        <resourceDirectory>${project.build.directory}/filtered-res</resourceDirectory>
      </configuration>
    </plugin>
  </plugins>
</build>

有几种方法来定义取代的价值，您可以在外部属性定义他们的属性，Maven的插件文件。为简单起见，我preFER使用Maven配置文件和pom.xml中定义它们，就像这样：

There are several ways to define the substituted value, you can define them in an external properties file with properties-maven-plugin. For simplicity, I prefer to use Maven profiles and define them in pom.xml, like so:

<profiles>
  <profile>
    <id>dev</id>
    <properties>
      <config.server.url>dev.company.com</config.server.url>
    </properties>
  </profile>
  <profile>
    <id>Test</id>
    <properties>
      <config.server.url>test.company.com</config.server.url>
    </properties>
  </profile>
  <profile>
    <id>Prod</id>
    <properties>
      <config.server.url>prod.company.com</config.server.url>
    </properties>
  </profile>
</profiles>

然后使用 MVN全新安装-Pxxx 来建立相应的APK。

Then use mvn clean install -Pxxx to build corresponding apk.
