Nested support-library dependency in travis

[gabrielemariotti]

Honestly, I don't know if it can be considered an issue.
My library doesn't require the support-library, but uses a dependency (Etsy staggered grid) that requires it.

Locally I can build the lib without any problems.
When I build in travis,without calling an explicit sdk-update for the Support library repository, I've a failed build.

> Could not find any version that matches com.android.support:support-v4:19.0.+.

My dependencies:

dependencies {    
    compile project(':library')    
    compile 'com.etsy.android.grid:library:1.0.4'
}

Log on travis:

Adding in travis.yml the sdk update for support library/repository it can work.

We should be able to do this. I'm actually surprised it doesn't work already.

I trapped in the same today - transitive dependency of support library was not downloaded. I run gradlew without installed android studio, android sdk and exported ANDROID_HOME variable

UPD. The transitive dependency for Robolectric which has testCompile and androidTestCompile scope

@gabrielemariotti @JakeWharton Travis supports downloading the Android SDKs in it's own way. Are you still seeing this issue?

[IgorGanapolsky]

@jaredsburrows I am curious about this too, and what impact this library will have on current Travis-ci build.

[jaredsburrows]

@IgorGanapolsky Well I do not use this plugin with Travis because you can use the .travis.yml config file.

Right now plugin scans only top level dependencies, listed at the build.gradle.
https://github.com/JakeWharton/sdk-manager-plugin/blob/master/src/main/groovy/com/jakewharton/sdkmanager/internal/PackageResolver.groovy#L272
To understand, that next library has nested child dependency

dependencies {    
    compile 'com.etsy.android.grid:library:1.0.4'
}

In general case it is required to make internet connection to the repository to download pom file, for example.
Which means, that plugin wouldn't do local scan anymore and those numbers from the readme

It currently takes about 100ms on average to check all of the above conditions.

may no longer be true. Yes, gradle will do this scan anyway to determine if all dependencies are present for the build and can cache already downloaded values, but do we want to do it at the plugin? May not be obvious why for the plugin users.
