mit Maven eine ausführbare Jar bauen

[matze86]

Ich habe eine Spring boot Anwendung gebaut und möchte über Eclipse mit Maven eine ausführbare JAR-Datei bauen.

Mein Vorgehen: auf pom.xml dann > Ausführen als > Maven Build > dann unter Goals habe ich package eingetragen und ausgeführt.

Mein Betriebssystem ist Ubuntu.
Danach habe ich die JAR-Datei ausführbar gemacht und bin in den Ordner gewechselt und mit "java -jar ./mein.jar" ausgeführt.
Aber es kommen Fehler wie z.B.

Error starting ApplicationContext. To display the condition evaluation report re-run your application with 'debug' enabled.
2023-01-10T18:23:30.213+01:00 ERROR 15460 --- [           main] o.s.boot.SpringApplication               : Application run failed

org.springframework.context.ApplicationContextException: Failed to start bean 'webServerStartStop'

Was mache ich hier falsch?

 

[KonradN]

Da wird doch bestimmt mehr sein. Da dürfte mindestens eine Exception mit Stacktrace sein, die anzeigen dürfte, wieso der webServerStartStop bean nicht gestartet werden konnte. Diese Informationen solltest Du uns nicht vorenthalten.

[KonradN]

So Stacktraces werden von hinten nach vorne gelesen, da halt irgendwo eine Exception auftritt, gefangen wird und dann in einer neuen Exception sozusagen mitgegeben wird.

Und damit ist der Fehler direkt hier zu sehen:

Caused by: java.net.BindException: Die Adresse wird bereits verwendet

Die Adresse, die da genutz werden soll, ist bereits in Nutzung. Es läuft also ggf. noch eine Version in der IDE, die Du erst stoppen musst, damit der Port frei ist.

 

[matze86]

Hat funktioniert, habe einfach Eclipse geschlossen. Vielen dank

 

[KonradN]

Eclipse darf laufen, nur eben wird sich die Spring Boot Applikation den Port (vermutlich 8080) schnappen, wenn Du diese in Eclipse startest. Du kannst diese dann aber auch einfach beenden ohne Eclipse zu beenden. Dazu solltest Du beim Console Fenster mit der Ausgabe der Spring Boot Applikation eine rote, quadratische Schaltfläche haben.

 

[matze86]

Dazu solltest Du beim Console Fenster mit der Ausgabe der Spring Boot Applikation eine rote, quadratische Schaltfläche haben.

Die rote Schaltfläche war aber aus.

 

[httpdigest]

Man kann in Eclipse auch mehrere Prozesse starten. Hier kann man dann in der Console View den entsprechenden Prozess auswählen. Erst dann erscheint dort auch ein rotes Rechteck zum Beenden dieses Prozesses. Vielleicht hattest du den nur in der Console View nicht ausgewählt.
