MojoExecutionException: Maven with Android

Question

I'm using Android Studio with Maven 3.1.1 and in the package goal it crashes with a MojoExecutionException. I have readed lot of posts but I can't get the solution.

[ERROR] Error when generating sources.

Answer 1

This issue was a little tricky, but can be solved!

First, when you get an error message like the one you got, you should try to run the command which Maven said it failed to run, because after maven downloads dependencies and builds code etc.. Maven it self runs the initial command to make your apk. At your case it is:

C:\Users\hvalls\AppData\Local\Android\android-studio\sdk\build-tools\19.0.3\aapt.exe package -f --no-crunch -I C:\Users\hvalls\AppData\Local\Android\android-studio\sdk\platforms\android-19\android.jar -M C:\Users\hvalls\Desktop\my-app\AndroidManifest.xml -S C:\Users\hvalls\Desktop\my-app\res -A C:\Users\hvalls\Desktop\my-app\target\generated-sources\combined-assets\assets -m -J C:\Users\hvalls\Desktop\my-app\target\generated-sources\r --output-text-symbols C:\Users\hvalls\Desktop\my-app\target --auto-add-overlay

So when you run this it will give you the real error output of the dx.bat tool. Just fix the errors that you see at output and rerun the mvn.

In my case I got this error because one of the image under my res folder is not a png file although the extension is png. After I fixed the file type it worked.

Answer 2

I had the same error and it costed me 2.5 working days to figure out the problem. The problem actually is too long pathes on your file system! yes, too long file path!

I moved the project from:

C:\work\workspaces\intelliJ\dory3

to

C:\work\n\dory

and it instantly worked. No errors while building, no problems in IntelliJ.

Answer 3

Error message does not say much, but it means that building your android apk failed. if you look at maven output above error, you might see message with actual error. in my case it was:

Extracting libs
Generating R file for Planer:AndroidApk:apk:1.0.0
C:\NetBeansProjects\Planer\AndroidApk\res\values\strings.xml:30: error: Resource entry ui.separator is already defined.
C:\NetBeansProjects\Planer\AndroidApk\res\values\strings.xml:29: Originally defined here.

Error when generating sources.
org.apache.maven.plugin.MojoExecutionException: 
    at com.jayway.maven.plugins.android.phase01generatesources.GenerateSourcesMojo.generateR(GenerateSourcesMojo.java:894)
    at com.jayway.maven.plugins.android.phase01generatesources.GenerateSourcesMojo.execute(GenerateSourcesMojo.java:323)
...
Caused by: com.jayway.maven.plugins.android.ExecutionException: ANDROID-040-001: Could not execute: Command ....
...

as you can see information about problem is typed above maven error. Mine problem, for example, was duplication of string resource- for some reason Android studio have made a duplicate. So, you do not have to run that command on your own. just look at the output.
