missing artifact com.android.support:support-v4:jar:21.0.0-rc1

[simongladkoskok]

Hi I am new to Maven. I am trying to convert existing Eclipse Android project to Maven Central. Its an open source project. support-v7-appcompat, support-v7-mediarouter and appcompat_v7 are dependencies in the project. So I used sdk deployer to add to local repo. But it gives me an error missing artifact com.android.support:support-v4:jar:21.0.0-rc1 in Eclipse and when I am trying to mvn clean install.
Here is my POM file.
Please help.

Same problem here

[mstevens83]

Run this: mvn install -pl repositories/android-m2repository

I have the same problem.

I want to use the appcompat-v7 library as an aar. So I do

    mvn clean deploy

within maven-android-sdk-deployer/repositories, then I look up the artifact on my nexus and find

    <dependency>
        <groupId>com.android.support</groupId>
        <artifactId>appcompat-v7</artifactId>
        <version>21.0.0</version>
        <type>aar</type>
    </dependency>

The problem is, appcompat-v7 depends on v4, to be exact it depends on

    com.android.support:support-v4:jar:21.0.0:compile

which is not deployed from the /repositories folder. Only an aar is deployed from it (which would be fine for me, if appcompat-v7 would use it)
And if I do a

    mvn deploy

from the maven-android-sdk-deployer/extras/compatibility-v4 folder I get a

    <dependency>
        <groupId>android.support</groupId>
        <artifactId>compatibility-v4</artifactId>
        <version>21.0.1</version>
    </dependency>

on my nexus which wont be recognized by appcompat.

Soooo I have no idea what to do, how to add v4 and v7-appcompat to my pom to be ready to build it via maven :-(

[degill]

So basically, adding this to my pom does not work:

<dependency>
    <groupId>com.android.support</groupId>
    <artifactId>support-v4</artifactId>
    <version>21.0.0</version>
    <type>aar</type>
</dependency>

<dependency>
    <groupId>com.android.support</groupId>
    <artifactId>appcompat-v7</artifactId>
    <version>21.0.0</version>
    <type>aar</type>
</dependency>

[mingfai]

for the particular problem of missing "com.android.support:support-v4:jar:21.0.0:compile", other than exclude it with:

            <groupId>com.android.support</groupId>
            <artifactId>appcompat-v7</artifactId>
            <version>21.0.0</version>
            <type>aar</type>
            <exclusions>
                <exclusion>
                    <groupId>com.android.support</groupId>
                    <artifactId>support-v4</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

you can also install it by

1. edit $ANDROID_SDK_HOME/extras/android/support/source.properties to ensure Pkg.Revision is correct
   for mac, it's /Applications/android-sdk-macosx/extras/android/support/source.properties
2. install the jar with
   mvn install -pl extras/compatibility-v4 -Dextras.compatibility.v4.groupid=com.android.support -Dextras.compatibility.v4.artifactid=support-v4

for my case, installing the jar removed a warning but doesn't seem to help to get it work.

as there are maven directory structure provided for the aar, instead of rely on maven-android-sdk-deployer to copy the aar around, I added a repository definition as follows:

<repositories>
        <repository>
            <id>android-local</id>
            <url>file:/Applications/android-sdk-macosx/extras/android/m2repository</url>
        </repository>
    </repositories>

The only way to heal this I've found is following. Yes, it's really bad and should be used extremely careful (till the day Android guys fix their provided maven repo).

Navigate to location of appcompat-v7 pom.xml in your local repository and open it for editing. And insert 'aar' to 'support-v4' dependency. Like this:

<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.android.support</groupId>
  <artifactId>appcompat-v7</artifactId>
  <version>21.0.2</version>
  <packaging>aar</packaging>
  <dependencies>
    <dependency>
      <groupId>com.android.support</groupId>
      <artifactId>support-v4</artifactId>
      <version>21.0.2</version>
      <type>aar</type>     
      <scope>compile</scope>
    </dependency>
  </dependencies>
</project>

[mstevens83]

Perhaps maven-android-sdk-deployer could be made to automatically insert that <type>aar</type line the pom.xml when appcompat-v7 is being installed to the local repo?
(At least until Google fixes it on their end)

[mosabua]

If you send a pull request that does that .. I can merge it.

[mstevens83]

I might have a go at that next week ;-)
