executing jar file created from maven build
I have created a jar file through mvn clean install. In pom.xml I specified the name of main class as well.
<configuration>
<archive>
<manifest>
<mainClass>com.amdocs.som.dashboard.report.MainClass</mainClass>
</manifest>
</archive>
</configuration>
When I try to execute the jar with java -jar app.jar, it gives me error saying no main manifest attribute, in app.jar and when I specify the main class name as well with this command java -cp app.jar com.dashboard.report.MainClass, it gives my NoClassDefError for javax/mail/MessagingException.
PS: If I execute the code from eclipse, it works fine without any issue
you can use spring-boot plugin to create a fat jar with dependencies. Add this to your pom.xml
<build>
<plugins>
.... other plugins.
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>1.5.2.RELEASE</version>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
<configuration>
<classifier>spring-boot</classifier>
<mainClass>com.amdocs.som.dashboard.report.MainClass</mainClass>
<executable>true</executable>
</configuration>
</execution>
</executions>
</plugin>
</build>
</plugins>
Now when you do a mvn clean install . it will create 2 jars one with -spring-boot is what you should execute.
