AAPT2 failing to merge resources on Docker

I'm trying to build an Android application inside a docker container on a CI server and aapt2 is failing to merge the resources.
Base Docker Image is openjdk:8-alpine
The packages being installed in my image from alpine repositories are:
build-base alpine-sdk bash ca-certificates curl gcc git gzip musl-dev openssh-client python python-dev tar unzip wget
Also I'm downloading and installing Glibc from
https://github.com/sgerrand/alpine-pkg-glibc/releases/download/2.25-r0/glibc-2.25-r0.apk
The installed android sdk packages are
build-tools;26.0.0-rc2 platforms;android-25 platform-tools extras;android;m2repository extras;google;m2repository extras;google;google_play_services
The application is currently using Gradle Wrapper 4.0-rc-1
The error is:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:mergeDebugResources'.
> Error: java.lang.ExceptionInInitializerError
* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:mergeDebugResources'.

BUILD FAILED in 30s
I tried installing different alpine packages with no luck.
I have the feeling that this is related to Glibc and/or Musl libraries, but I don't understand it enough not to know how to solve this problem
Also, everything works fine on a very similar image (alpine based too) with build-tools 25.0.3 and Gradle 3.5.
Any clues? Thanks

I stumble upon the same error. The problem as you suspected is that Alpine Linux ships with Musl instead of GNU libc, the Android SDK tooling requires glibc.
You could use something like this: https://github.com/frol/docker-alpine-glibc, or create a similar image on your own if you're comfortable with someone else compiling glibc for you.

You can check which libraries are missing (ENOENT singal) with: $ strace ./aapt2
Then try to create a simbolic link of those libraries to the expected path.

Jenkins gradle sonarQube Android

I have to setup a job on Jenkins to build an Android Application. I have also a SonarQube server which is accessible at http://x.x.x.198/sonar.
I added a shell script that will be called to launch sonarqube analysis on the project.
SonarQube server and Jenkins run on different server, and I can access to the SonarQube host from Jenkins machine.
The build failed and here is the console output:
./gradlew sonarqube --stacktrace -Dsonar.url.host=http://x.x.x.198/sonar
Parallel execution with configuration on demand is an incubating feature.
Incremental java compilation is an incubating feature.

Finished: FAILURE
Has anyone already faced this problem? Need help :|
Thanks in advance.

Finaly found why it doesn't work. In my gradle.properties, i had specified some proxy properties. I have removed these entries (host, port, login, password, ...) so when sonarqube task is called, gradle does not use any proxy to access the SonarQube server. The task finished successfully on Jenkins and analysis reports uploaded to sonarqube server :).
This post helped me Sonarqube grade build failed with "SonarQube server [http://x.12.11.18:9000] can not be reached"
Hope this will help others.

2.7.1 is not back-compatible. Lock your plugin version to 2.6 in your pom.xml or upgrade your SonarQube
Workaround: Adding -Dsonar.host.url=http://my.server:9000 to mvn command works for me
Better than disabling the plugin, you may fix the plugin version to
2.6, which works fine, taking into account sonar.host.url.
For instance, with Maven in my case:
<pluginManagement>
</plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>sonar-maven-plugin</artifactId>
<version>2.6</version>
<!-- sonar.host.url not working with version 2.7 -->
</plugin>
</plugins>
</pluginManagement>

connectedAndroidTest launched via gradle doesn't complete

I have over a hundred Espresso tests. Once in a while, when I launch them using ./gradlew clean cAT the tests complete on the connected device, in my case Genymotion emulator, but when they're done, the gradle task is stuck in the terminal at Building 96% > : <appname>:connectedAndroidTest . I can close the task with CTRL+C, but as it doesn't complete normally, no html output is produced.
EDIT:
10 minutes after the tests had concluded this is produced in the terminal (-d flag):

When I try to build and run my app in cordova, I get this error. I have no idea what to do! Any advice? Thanks everyone!

Hello every one I am working on android boot strap for that I follow this link and I configure Maven on my linux machine. I also use Intellij for Android but I have some error.

I had a similar problem when doing maven clean.
it was using maven-clean-plugin version 2.2 by default.
i forced version 2.5 by adding the following to my build and that solved the problem:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-clean-plugin</artifactId>
<version>2.5</version>
</plugin>
