Tomcat 7 and Spring boot war start up

I get the following message when I deploy my war to the Tomcat 7:
nested exception is java.lang.NoClassDefFoundError: javax/el/ELManager
I added <tomcat.version>7.0.61</tomcat.version> to my pom.xml and can now reproduce the error on my development environment.
The error happens after the bean creation, the other changes that were necessary to get the war to run I made.
I tried to change my pom.xml so that it uses old versions which might play nice with tomcat 7, but failed to remove the problem. I don't know which package produces the problem.
See pom.xml:

spring boot 2.1.2 release supports any Servlet 3.1+ compatible container.
Tomcat 7 is not one of them
spring boot docs
Use tomcat 8 or beyond http://tomcat.apache.org/whichversion.html

Spring Boot 2.1 requires a Servlet 3.1 compatible container. Tomcat 7 is a Servlet 3.0 container so you cannot use it with Spring Boot 2.1.
You'll need to upgrade to Tomcat 8.5.x or 9.0.x.

It is because javax/el/ELManager was introduced in el-api 3.0 and tomcat 7 is using el-api 2.2 so this class is not present in it.
Please make sure your dev and prod environment are the same when you are developing.
Or you can add following dependency in your pom.xml
<dependency>
<groupId>javax.el</groupId>
<artifactId>javax.el-api</artifactId>
<version>3.0.0</version>
</dependency>

Maven project building fails at test-compile stage with NoClassDefFoundError and others

I'm totally lost with the unhelpful Maven trace. mvn compile succeeds like a charm but with mvn package, the tests (of this particular quickstart tutorial) fail with NoClassDefFoundError, NoSuchMethodError at test-compile stage (with -DskipTests=true option emitting that stage it works successfully) of the Maven build process. Also, projects fails at runtime with those errors.
I have this problem in my own project, and to go through the proper mvn install and project initialization from an archetype I ended up to go through the process with a bear bone tutorial.
When compiled and packaged on a remote machine (OS is Ubuntu 16.04, local is OS X), it packages and compiles normally. With the local machine, not.

Maven adding jars to war which are not present in dependency:tree

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.

(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?

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

Class path contains multiple SLF4J bindings, log back-classic and log4j

getting below error when i try to run unit test in my java project:
SLF4J: Class path contains multiple SLF4J bindings.

Found the problem. It was in /.classpath. I compared the class path file with a working project and deleted any additional references. And it worked.
The bad class path had alot of jar specific references like below
<classpathentry kind="var" path="M2_REPO...
Below is a diff b/t bad class path file on left, and correct class path file on right.
I have no idea on how those class path entry got in.

issue with maven dependency?

Any ideas?

From twilio:
Hi Matthew,
Thanks for checking with us.
It looks like "foursquare-api" is bringing in the
"appengine-api-1.0-sdk" dependency.
[INFO] +- fi.foyt:foursquare-api:jar:1.0.2:compile
[INFO] | +- org.json:json:jar:20090211:compile
[INFO] | \- com.google.appengine:appengine-api-1.0-sdk:jar:1.6.5:compile
You can try excluding this dependency, however I expect it will
probably break the "foursquare-api" library.
"twilio-java" does not have a hard dependency on App Engine for this
reason.
Please let us know if you have any other questions.
