NoClassDefFoundError: com/sun/mail/util/MailLogger
Wenn man die Fehlermeldung bekommt
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/MailLogger at javax.mail.Session.initLogger(Session.java:283) at javax.mail.Session.(Session.java:268) at javax.mail.Session.getDefaultInstance(Session.java:378) at javax.mail.Session.getDefaultInstance(Session.java:418) at eu.masterdevops.sendmail.App.main(App.java:25) Caused by: java.lang.ClassNotFoundException: com.sun.mail.util.MailLogger at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:583) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:178) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521) … 5 more
dann fehlt vermutlich eine Abhängigkeit in der pom.xml:
<dependency> <groupId>com.sun.mail</groupId> <artifactId>javax.mail</artifactId> <version>1.6.2</version> </dependency>
