android-maven-plugin和资源过滤

Question

我是maven的新手并试图配置它用android-maven-plugin构建我的android项目.我在assets目录中有一个application.properties文件,其中包含不同的应用程序设置.我想从我的pom中获取这些价值.在属性文件中,我将一个属性定义为

myFilteredProperty=${helloFromPOM}

并在POM中定义相同的属性:

    <properties>
        <helloFromPOM>MY PROPERTY</helloFromPOM>
    </properties>

切换资产dir上的过滤

<build>
    ...
    <resources>
        <resource>
            <directory>${project.basedir}/assets</directory>
            <filtering>true</filtering>
        </resource>
    </resources>
    ...
</build>

并为android-maven-plugin的示例配置recources 插件

        <plugin>
            <artifactId>maven-resources-plugin</artifactId>
            <executions>
                <execution>
                    <phase>initialize</phase>
                    <goals>
                        <goal>resources</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

但是当我试图在我的应用程序中使用此属性显示Toast时,我看到$ {helloFromPOM}而不是MY PROPERTY.

在我的maven生成的目标目录中,我在两个地方看到这个属性文件:

• /target/generated-sources/combined-assets/assets/application.properties
• /target/myapp-0.0.1-SNAPSHOT.apk\application.properties

首先是错误的,它包含$ {helloFromPOM}而不是MY PROPERTY.其次,apk文件内部是正确的.但是当我在设备上安装这个apk时,它显示错误的值$ {helloFromPOM}.

我做错了什么？

谢谢你的回答,我尝试了,但得到这个错误:

当我<resourceDirectory>${project.build.directory}/filtered-assets</resourceDirectory>在POM中评论时,构建完成成功,但它不使用过滤后的组件.

此外,我尝试cmd.exe /X /C ""C:\Program Files\Android\android-sdk\platform-tools\aapt.exe" package -m -J D:\projects\myapp\target\generated-sources\r -M D:\projects\myapp\AndroidManifest.xml -S D:\projects\myapp\target\filtered-assets --auto-add-overlay -A D:\projects\myapp\assets -I "C:\Program Files\Android\android-sdk\platforms\android-8\android.jar""在我的命令行中执行此操作并得到此错误:invalid resource directory name: D:\projects\myapp\target\filtered-assets/application.properties.在过滤资产之后,错误的斜杠反而斜线反斜杠.更改<resourceDirectory>${project.build.directory}/filtered-assets</resourceDirectory>到<resourceDirectory>${project.build.directory}\filtered-assets</resourceDirectory>也于事无补.

PS我的插件部分看起来像这样

        <artifactId>maven-resources-plugin</artifactId>
        <executions>
            <execution>

Answer 1

现在它有效,我<resourceDirectory>${project.build.directory}/filtered-assets</resourceDirectory>改为<assetsDirectory>${project.build.directory}/filtered-assets</assetsDirectory>.结果POM:

<properties>
    <myProperty>MY PROPERTY!!!!111</myProperty>
</properties>

    <resources>
        <resource>
            <directory>${project.basedir}/assets</directory>
            <filtering>true</filtering>
            <targetPath>${project.build.directory}/filtered-assets</targetPath>
            <includes>
                <include>**/*.properties</include>

        </resource>
