How to tell mvn to use local folder to solve Local Dependency issue for zxing's Android project

I downloaded zxing and tried to build it locally with mvn.
I got some problem, when I try to build android project (to make it a jar other than apk file), I got this error:

I put android-core-3.1.1-SNAPSHOT.JAR AND core-3.1.1-SNAPSHOT.JAR into the libs folder of android project, but it doesn't help at all.
what I am doing wrong? The pom file under android folder is

This is just a Maven question. You have downloaded source code for master, so points to SNAPSHOT builds. If you really want to use that, you need to mvn install to create snapshot artifacts locally. Here you just went straight to android/ and built it, but that won't work. Just build everything from the top level and it will work.
This is described at https://github.com/zxing/zxing/wiki/Getting-Started-Developing except that if you are building snapshots off master you need to mvn install not mvn package.

PhoneGap/Cordova: Libs does not exist

I've just downloaded Cordova, along with all the requirements for Android and Windows Phone. I can successfully build a WP8 image and send it to my 8X, however, I can't seem to be able to build an Android image.
When I execute cordova build android, I get the following error:
Generating config.xml from defaults for platform "android"
Preparing android project

And when I launch the build command manually, I get the following error:

It seems that the cordova-3.3.0.jar file doesn't get compiled, shouldn't it get compiled automatically? Is there anything I'm missing?

It can be an error with Ant. I had this error because I forgot to change the environment variable path.
The path I added was wrong (you need to specify this folder: "way\to\apache-ant-1.9.3\bin"). I just changed it and it works now.
(If it's not that, it can be an other path environment variable such as node, or your java sdk or android sdk)
Hope it can help someone.

I just deleted the whole Android project, recompiled the CordovaLibs and recompiled the Android project. Seems to have fixed it.

try commands
cordova platform rm android
cordova platform add android
cordova build android

Android Maven Could not find tool 'aapt'

i was trying to follow this tutorial:
http://www.gdgankara.org/2012/11/01/step-by-step-android-development-with-maven/
but after setting up the environment, and create a project, at the "run as\maven install" step i got this:

SLF4J: Defaulting to no-operation (NOP) logger implementation

I've tried lot of times, but with no luck.
I have Eclipse Juno on Windows7 64 bit, APK Tool installed and Maven 3.0.5.
It seems a well known problem for maven staff:
https://code.google.com/p/maven-android-plugin/issues/detail?id=104
but it should be solved from ages...
My Environment User variables:
M2_HOME=C:\Program Files\Java\apache-maven-3.0.5
ANDROID_HOME=C:\adt-bundle-windows-x86_64-20130514\sdk
My Environment System variable:
Path=......;%ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools;%ANDROID_HOME%\build-tools;%ANDROID_HOME%\platforms;%M2_HOME%\bin;%ANDROID_HOME%\build-tools\android-4.2.2
Does anybody know how to workout this trap?
thanks!

I also encountered the same problem when using latest ADT from google and trying to compile the bootstrap android platform.
The latest r17 build separate out aapt to build-tools folder. Hence it is maven-android-plugin cannot support it.
See issue discussed here.
Tried and working:
cd $ANDROID_HOME/platform-tools
ln -s ../build-tools/android-4.2.2/aapt aapt
ln -s ../build-tools/android-4.2.2/lib lib
ln -s ../build-tools/android-4.2.2/aidl aidl
Some installations may be structured using the API version:
cd $ANDROID_HOME/platform-tools
ln -s ../build-tools/17.0.0/aapt aapt
ln -s ../build-tools/17.0.0/lib lib
ln -s ../build-tools/17.0.0/aidl aidl
Keep in mind that this is fixed in the latest version (>3.5.3) of the Android Maven Plugin, as other answers point out.

Update:
This has been resolved since Android Maven Plugin v3.6.0. For now you will only need these symlinks if you use IntelliJ v12.x. IntelliJ v13 EAP+ should work out of the box.
Original answer:
This has been fixed and will be released with Android Maven Plugin v3.5.4. See the github pull request:
Upgraded AndroidSdk to use path and platform utilities from sdklib
You can try validating the snapshot build which contains the fix by adding the following to your pom.xml:
<plugin>
<groupId>com.jayway.maven.plugins.android.generation2</groupId>
<artifactId>android-maven-plugin</artifactId>
<version>3.5.4-SNAPSHOT</version>
...
</plugin>
...
<pluginRepositories>
<pluginRepository>
<id>oss.sonatype.org-jayway-snapshots</id>
<name>Jayway OpenSource SNAPSHOTs on Sonatype.org</name>
<url>http://oss.sonatype.org/content/repositories/jayway-snapshots/</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
</pluginRepository>
</pluginRepositories>
Please provide feedback on the developer group:
New snapshot for 3.5.4 available

If you are using Windows, the symbolic linking can be done using mklink command.
D:\>cd "Program Files (x86)\Android\android-sdk"
D:\Program Files (x86)\Android\android-sdk>cd platform-tools
D:\Program Files (x86)\Android\android-sdk\platform-tools>mklink aapt.exe ..\build-tools\17.0.0\aapt.exe
symbolic link created for aapt.exe <<===>> ..\build-tools\17.0.0\aapt.exe
D:\Program Files (x86)\Android\android-sdk\platform-tools>mklink aidl.exe ..\build-tools\17.0.0\aidl.exe
symbolic link created for aidl.exe <<===>> ..\build-tools\17.0.0\aidl.exe
D:\Program Files (x86)\Android\android-sdk\platform-tools>mklink /d lib ..\build-tools\17.0.0\lib
symbolic link created for lib <<===>> ..\build-tools\17.0.0\lib

I get stuck with the same problem. Finally i managed to resolve the issue after two hours. To make it simple and resolve the issue in 5 minutes i listed the steps below
Step 1 - In Eclipse update your Android Maven Plugin to 0.4.3.2013 using the beta release link
http://rgladwell.github.io/m2e-android/updates/master/
Step 2
<plugin>
<groupId>com.jayway.maven.plugins.android.generation2</groupId>
<artifactId>android-maven-plugin</artifactId>
<version>3.6.1</version>
<configuration>
<sdk>
<platform>17</platform>
</sdk>
</configuration>
</plugin>
It will solve the following issues
"No Android Platform Version/API Level has been configured"
Could not find tool 'aapt'
Hope it helps

I too had similar problems.
Solved by following steps :
1) Upgrade maven to 3.1.1
2) Use android-maven-plugin 3.6.1 pr greater [I used 3.8.0]
3) Use maven-dependency-plugin 2.8
If you want to build against latest Android SDK [ex : 4.3], follow following additional steps -
4) Install the local copy of android.jar using command mvn install:installFile ..
5) Set 18
Hope this helps.

I'm using macOS 10.14 and in my case:
I download Android packaging tool from AAPT and then copied all the files into $ANDROID_HOME/platforms/$SDK/tools/
DON'T REMIND CHANGE $SDK WITH YOUR REAL NAME SDK FOR INSTANCE android-29

Unable to do maven clean install

I am new to this maven concept, I am building one android application for which I am want to robospice lib. Rebospice demo example need maven clean install. I installed maven on my ubuntu 12.04

Whats the problem behind this.. Need help to solve this problem....

You probably have to configure your maven repositories (You tell maven where to get the dependencies)
OR
Something went wrong the first time you tried to download the artefact.
If this is the later, you can solve the problem by browsing your ".m2" folder and go and see if the corresponding folder contains just metadata files or if it contains the jar and the pom as well. I something looks wrong, you can just delete the folder and retry to build your project.
By the way, it seems that this project "robospice" has a more recent version available (and stable, not snapshot), so you might want to try to use 1.3.1 instead of 1.0.0 SHAPSHOT, if it fits with your project needs.

MyProj is a clean project created via:
android create project --name MyProj --package com.myproj --target "android-15" --path MyProj --activity MyProj
of course file "/usr/share/android-sdk-linux/tools/ant/build.xml" exist.
"ant help" from shell runs fine.
local.properties contains valid path to android SDK:
sdk.dir=/usr/share/android-sdk-linux
Any idea why MyProj/build.xml cannot find "/usr/share/android-sdk-linux/tools/ant/build.xml" ?

Ok, I managed to solve it. User jenkins had no permission to enter android-sdk-linux folder.
In general, when debugging such issues it is very helpful to try to do manually what Jenkins is doing:
$sudo su jenkins
And now, as jenkins user try to enter folders, create new one etc.
