Issue
I've recently prepared spring-boot configuration to work properly on a standalone jetty.
I've encountered a strange behavior from maven. It adds jars to my .war archive which are not present in mvn dependency:tree. I've worked around the problem by adding this to my pom.xml:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<packagingExcludes>WEB-INF/lib/tomcat-*.jar</packagingExcludes>
</configuration>
</plugin>
But that's obviously an ugly solution.
pom.xml:
<?xml version="1.0" encoding="UTF-8"?>

(Yes, there is one tomcat lib in the tree, but there are several added to .war)
Unwanted jars:
tomcat-embed-core-8.0.26.jar
tomcat-embed-logging-juli-8.0.26.jar
tomcat-embed-websocket-8.0.26.jar
tomcat-jdbc-8.0.26.jar
tomcat-juli-8.0.26.jar
Here's a link to the sample application.
What is adding the tomcat* jars to my .war? How can I stop it doing so?
Solution
Well when I run maven package this pom produces two war files one named "spbj-example.war" for running with
org.springframework.boot.loader.WarLauncher
and another one named "spbj-example.war.original".
You should use the second war which doesn't contain anything related to servers. The first one contains a lib directory in which you have jar files to run a server like "jetty-server-9.2.13.v20150730.jar" and lots of others.
So most likey problem is related to your dirty "target" directory. You should use
mvn clean package/install
