Failed to execute goal org.codehaus.mojo exec-maven-plugin - spring

Question

I have an issue that I spend 5 days without resolving it:
When executing mvn exec:java it fails to correctly parse the configuration arguments, throwing the following error:
"Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.1:java (default-cli) on project poll-translator: An exception occured while executing the Java class. null: InvocationTargetException: Error creating bean with name 'serviceLocator' defined in class path resource [META-INF/dsol/dsol.xml]: Cannot resolve reference to bean 'dsol-service-proxy' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dsol-service-proxy' defined in class path resource [META-INF/dsol/dsol.xml]: Instantiation of bean failed; nested exception is net.sf.cglib.core.CodeGenerationException: java.lang.NullPointerException-->null -> [Help 1]"
This is the POM configuration used file (using Apache Maven 3.0.4):

Answer 1

The problem is with your spring configuration and not with your maven config.
In your case, when spring tries to create dsol-service-proxy object its constructor requires
serviceLocator which inturn creates serviceLocator and spring encountered some problem in creating your serviceLocator. Check your dsol.xml and make sure serviceLocator is configured correctly.

Answer 2

Another possible solution is that if you have something like this <argument>${env.ANDROID_HOME}/build-tools/android-4.2.2/lib/dx.jar</argument>
, consider adding ANDROID_HOME to environment path variables.
