I encountered this issue in eclipse only, everything worked fine in Maven command line, and my web.xml file existed. It was a mature project (already deployed out in production) that was impacted. My problem was tied to the eclipse metadata. There was an issue with one of the files in my .settings/ folder, specifically org.eclipse.wst.common.component had been changed. I was able to restore this file to its prior version, which resolved the issue in my case.

Note that Yuci's answer did not work for me, when I tried to click on Deployment Assembly in the eclipse properties, I got an error that said "the currently displayed page contains invalid values."

If you already have web xml under  src main webapp WEB-INF but you still get error  web xml is missing and  is set to true   you could check if you have included  src main webapp in your project source    Here are the steps you can follow    You can check this by right clicking your project  and open its Properties dialogue  and then  Deployment Assembly   where you can add Folder  src main webapp  Save the setting  and then   Go to Eclipse menu Project -  Clean    and clean the project  and the error should go away      I verified this with Eclipse Mars

It doesn t make sense to create a web xml just elcipse wants it  even there is no need  This is the case if you have servlet conatiner embedded or living without xml cfg like spring-boot does  The you just diable JavaEE  useless stuff  in eclipse on project level or global  Eclipse STS gt Windows gt Preferences gt JavaEE gt Doclet gt Webdoclet gt   uncheck  DeploymentDescriptor  gt  OK

If you use Spring Tool Suite  option for Generate Deployment Descriptor Stub is moved under Java EE Tools  so you    Right click on your project Select Java EE Tools Select Generate Deployment Descriptor Stub option   This will create web xml file inside src main webapp WEB-INF  folder  and of course remove error from Maven s pom xml file

The step of   Select your project and select the  Deployment Descriptor  option and then choose  Generate Deployment Descriptor stub  works fine  The issue is that it is not always the case that we need web xml  so it is best to append    false to pom xml

This is a maven error  It says that it is expecting a web xml file in your project because it is a web application  as indicated by  lt packaging gt war lt  packaging gt   However  for recent web applications a web xml file is totally optional  Maven needs to catch up to this convention   Add this to your maven pom xml to let maven catch up and you don t need to add a useless web xml to your project    lt build gt       lt plugins gt           lt plugin gt               lt groupId gt org apache maven plugins lt  groupId gt               lt artifactId gt maven-war-plugin lt  artifactId gt               lt version gt 2 6 lt  version gt               lt configuration gt                   lt failOnMissingWebXml gt false lt  failOnMissingWebXml gt               lt  configuration gt           lt  plugin gt       lt  plugins gt   lt  build gt    This is a better solution than adding an empty web xml because this way your final product stays clean  your are just changing your build parameters   For more current versions of maven you can also use the shorter version    lt properties gt       lt failOnMissingWebXml gt false lt  failOnMissingWebXml gt   lt  properties gt

Eclipse recognizes incorrect default webapp directory  Therefore we should set clearly it by maven-war-plugin    lt build gt     lt plugins gt       lt plugin gt         lt groupId gt org apache maven plugins lt  groupId gt         lt artifactId gt maven-war-plugin lt  artifactId gt         lt version gt 3 0 0 lt  version gt         lt configuration gt           lt webappDirectory gt src main webapp lt  webappDirectory gt         lt  configuration gt       lt  plugin gt     lt  plugins gt   lt  build gt    Once saving this setting  the error will never occour if removed it   I cannot explain why
