Tomcat can't open because of maven in several situations

Question

These two days,I experience some issues with the maven(I am new to it),all result in the failure to open the tomcat.Here are a few situations:

1.After import maven project downloaded from github;

2.After changing the dynamic project to maven project;

3.After adding some dependencies to the pom.xml;

4.After changing databases linked to the maven project;

And there may be other situations which makes the tomcat opening problem.Is there any similar situations or any solutions?It's really disappointed that suddenly you can't open the tomcat,maybe just did a few things.If possible I wish there are some explanation.Thank you. And all the log are:

what do you mean by opening tomcat? Starting a tomcat service ? — Vinod Chandak, Jul 10 '17 at 12:08
some sort of it.The log is Server Tomcat v8.5 Server at localhost failed to start. — doctorrm, Jul 10 '17 at 12:10
All the situations have just the same exception.I've posted it. — doctorrm, Jul 10 '17 at 12:11
Are you taking properties from outside like from properties file? Or are there any checks on the start of your application? — npradeep357, Jul 10 '17 at 12:14
This is the project converted from dynamic project.It's fine before I change some mysql code and java logic and add a common-upload.jar.Now it's wrong...pom.xml has no problem except the common-upload.jar. commons-fileupload commons-fileupload 1.3 — doctorrm, Jul 10 '17 at 12:18
Now I know it's the problem with the apache commons-fileupload.jar .Tomcat was fine before I add it into my pom.xml file. — doctorrm, Jul 10 '17 at 12:25
@doctorwhorm what problem did you got after adding the jar dependency? — npradeep357, Jul 10 '17 at 12:25
Can't open the tomcat ,that's the problem I get.@npradeep357 — doctorrm, Jul 10 '17 at 12:27
Is it possible for you to paste the output of `mvn dependency:tree` command? — Rishikesh Darandale, Jul 10 '17 at 12:32
@Rishikesh,sorry,I am new to maven.Can't understanding what's the command it is. — doctorrm, Jul 10 '17 at 12:36
@doctorwhorm have you made maven build after adding dependency? — npradeep357, Jul 10 '17 at 12:39
No.@npraddep357. I just save it,and it automatically download the jar in the Maven Dependency.No other operation.I've posted the command output above. — doctorrm, Jul 10 '17 at 12:43
@doctorwhorm, please run it under your project directory on cmd. — Rishikesh Darandale, Jul 10 '17 at 13:35
@Rishikesh Darandal .Thank you all.I've solve it,I update the maven denpendencies by the link https://stackoverflow.com/questions/32090921/maven-invalid-loc-header-bad-signature and it works! And I've post the new cmd output above as you said.Thank you anyway. — doctorrm, Jul 10 '17 at 14:02

It is clearly saying that some of the following Class is not found :-

    org/apache/commons/fileupload/FileUploadException

You have to include this library into your project dependency library folder.

Get “commons-fileupload.jar” from official website – http://commons.apache.org/fileupload/

Get “commons-fileupload.jar” from Maven repository

<dependency>
   <groupId>commons-fileupload</groupId>
      <artifactId>commons-fileupload</artifactId>
   <version>1.2.1</version>
 </dependency>

You need to put commons-fileupload.jar and commons-io.jar to your WEB-INF/lib forlder. Classpath is used during build, but they must be available during runtime also.

Actually, if you had used IDE for Java EE development (like Eclipse) putting these Jars to WEB-INF/lib would be enough, as they would be automatically visible in the claspath for build.

If he hadn't already added this dependency, how come he didn't got any compilation issues? – npradeep357 Jul 10 '17 at 12:20
It can be the version Issues :) – Hasnain Ali Bohra Jul 10 '17 at 12:20
Now I know it's class-not-found problem.But I've already add it in my pom.xml file.I try some other versions. – doctorrm Jul 10 '17 at 12:22
I concur with the version issue theory. – Vinod Chandak Jul 10 '17 at 12:22
Please follow the Document https://www.mkyong.com/struts/java-lang-noclassdeffounderror-orgapachecommonsfileuploadfileuploadexception/ – Hasnain Ali Bohra Jul 10 '17 at 12:23
Awakawd......I haven't solve it.I don't know if it's the version problem.I am still figuring it.I've already change the version,still the same... – doctorrm Jul 10 '17 at 12:30
Okk @doctorwhorm which version you are using ? let me find the correct version of jar. – Hasnain Ali Bohra Jul 10 '17 at 12:33
1.3 – doctorrm Jul 10 '17 at 12:34
Thank you all.I've solve it,I update the maven denpendencies by the link https://stackoverflow.com/questions/32090921/maven-invalid-loc-header-bad-signature and it works.And sorry,@Hasnain Ali Bohra,my reputation is under 15,the system doesn't allow me to accept your answer...I tries it. – doctorrm Jul 10 '17 at 13:30
