Ich habe diesen Code:ClassNotFoundException, wenn sie mit Maven Ausführung aber keine Fehler mit Intellij
public static void main(String[] args) throws ClassNotFoundException {
ClassLoader scl = ClassLoader.getSystemClassLoader();
Class<?> c = scl.loadClass("junit.framework.TestCase");
System.out.println(c);
}
Es kompiliert und läuft ganz gut in IntelliJ (Ausgabe von class junit.framework.TestCase).
Aber wenn ich es mit Exec-Maven-Plugin mit läuft es scheitert.

Der Klassenpfad ist klar gebrochen, aber ich sehe nicht wo.
Hier ist der pom.xml Eintrag des Plugins, nur für den Fall.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.6.0</version>
<configuration>
<mainClass>istic.fr.vev_dynamic_testing.App</mainClass>
<arguments>

<classpath/>
</arguments>
</configuration>
</plugin>
POM enthält junit als Abhängigkeit (in 4,12, ohne scope Attribut).
Und was sehen Sie, wenn du machst es mit 'mvn -e'? –
Junit befindet sich normalerweise im Testumfang, der dem exec-maven-plugin nicht zur Verfügung steht. –
