Non riesco a eseguire una classe di test molto semplice utilizzando il runner Powermock test. Provoca un eccezione ExceptionInInitializerError. Sembra essere un problema con le dipendenze sul classpath, tuttavia, ho provato alcune varianti delle versioni di dipendenza, ma tutte causano lo stesso errore. Come posso far passare questo semplice test quando utilizzo il runner Powermock?PowerMockRunner causa ExceptionInInitializerError quando si esegue il test banale
Il codice di prova:
package net.solasistim.hello;
import org.junit.Test;
import org.junit.Assert;
import org.junit.runner.RunWith;
import org.powermock.modules.junit4.PowerMockRunner;
@RunWith(PowerMockRunner.class)
public class HelloTest {
@Test
public void testMain() {
Assert.assertTrue(true);
}
}

Esecuzione mvn clean compile test provoca il seguente output:
