Maven Android instrumentation test output -

as experiment, trying use maven build google android market licensing library, sample, , test projects. here pom.xml test project:

<?xml version="1.0" encoding="utf-8"?> <project xmlns="http://maven.apache.org/pom/4.0.0" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:schemalocation="http://maven.apache.org/pom/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">     <modelversion>4.0.0</modelversion>     <groupid>etherwalker.example</groupid>     <artifactid>license_test</artifactid>     <version>0.0.1-snapshot</version>     <packaging>apk</packaging>     <name>license - instrumentation tests</name>      <parent>         <groupid>etherwalker.example</groupid>         <artifactid>license_parent</artifactid>         <version>0.0.1-snapshot</version>     </parent>      <dependencies>         <dependency>             <groupid>com.google.android</groupid>             <artifactid>android</artifactid>             <scope>provided</scope>         </dependency>         <dependency>             <groupid>com.google.android</groupid>             <artifactid>android-test</artifactid>             <scope>provided</scope>         </dependency>          <dependency>             <groupid>junit</groupid>             <artifactid>junit</artifactid>             <scope>test</scope>         </dependency>          <dependency>             <groupid>etherwalker.example</groupid>             <artifactid>license_sample</artifactid>             <version>0.0.1-snapshot</version>             <type>apk</type>             <scope>provided</scope>         </dependency>         <dependency>             <groupid>etherwalker.example</groupid>             <artifactid>license_sample</artifactid>             <version>0.0.1-snapshot</version>             <type>jar</type>             <scope>provided</scope>         </dependency>      </dependencies>      <build>         <sourcedirectory>src</sourcedirectory>         <plugins>             <plugin>                 <groupid>com.jayway.maven.plugins.android.generation2</groupid>                 <artifactid>maven-android-plugin</artifactid>                 <extensions>true</extensions>             </plugin>         </plugins>     </build>  </project> 

when run mvn install in project, following error when android instrumentation unit tests run:

[info] c:\usr\android-sdk-windows/platform-tools/adb.exe [shell, am, instrument, -w, com.example.android.market.licensing.test/android.test.instrumentationtestrunner]   com.android.vending.licensing.aesobfuscatortest:.......  com.android.vending.licensing.obfuscatedpreferencestest:instrumentation_result: shortmsg=java.security.spec.invalidkeyspecexception  instrumentation_result: longmsg=java.security.spec.invalidkeyspecexception: java.io.eofexception: eof encountered in middle of object  instrumentation_code: 0 

what want know is, can find junit results, , stack trace exception?

this error appears when nothing test (your main project not build).

the structure of maven project must be:

your_project-parent

|--your_project

|--your_project-it

when

your_project - main project

your_project-parent - parent project

your_project-it - instrumental testing project

you must run mvn install on your_project-perent project.

then first builds main project test project.
