What is the right way to update android manifest with xbuild and Jenkins

Question

In our environment we are building xamarin.android project and would like to pass $(build_number) variable to Jenkins build. Unfortunately Jenkins is building the project as if nothing was passed to the build workflow.

I tried to use XmlPoke which works fine for windows and doesn't work on mac at all.

os: mac os x jenkins & xamarin are the latest stable version

Please suggest.

Answer 1

There is no default solution/plugin for it if you are building under Mac OS Host. You have to create your own script/tool with input parameters to update xml attributes to a given value. Then use it with shell exec task.

Answer 2

According to this link, you can access environment build variables in csproj file using $(VAR) notation.

So, predefined Jenkins variables, such as BUILD_NUMBER should be available directly inside your project use $(BUILD_NUMBER), nothing extra required during invocation.

Answer 3

I found a good solution from http://jonathanpeppers.com/Blog/xamarin-android-builds-in-jenkins

<Target Name="BeforeBuild" Condition=" '$(JENKINS)' == '1' ">
<XmlPoke XmlInputPath="Properties\AndroidManifest.xml" Namespaces="&lt;Namespace Prefix='android' Uri='http://schemas.android.com/apk/res/android' /&gt;" Query="manifest/@android:versionCode" Value="$(SVN_REVISION)" />
<XmlPoke XmlInputPath="Properties\AndroidManifest.xml" Namespaces="&lt;Namespace Prefix='android' Uri='http://schemas.android.com/apk/res/android' /&gt;" Query="manifest/@android:versionName" Value="2.0.$(SVN_REVISION)" />
</Target>

Use it in your .csproj file and don't forget to set 'JENKINS' as a global environment with a value of 1.
