java - spring-boot without parent pom.xml cannot generate war packaging -

i used example gs-convert-jar-to-war provided spring-io. describes how generate war packaging within spring boot project.

the spring-boot documentation allows using own parent poms, omitting predefined parent pom spring-boot projects. following dependency has added:

<dependencymanagement>     <dependencies>         <dependency>             <!-- import dependency management spring boot -->             <groupid>org.springframework.boot</groupid>             <artifactid>spring-boot-starter-parent</artifactid>             <version>1.0.1.release</version>             <type>pom</type>             <scope>import</scope>         </dependency>     </dependencies> </dependencymanagement> 

i applied change (and change) example. afterwards no longer possible generate war. following error message:

[error] failed execute goal org.apache.maven.plugins:maven-war-plugin:2.1.1:war (default-war) on project gs-convert-jar-to-war: error assembling war: webxml attribute required (or pre-existing web-inf/web.xml if executing in update mode) -> [help 1] 

here complete listing of modified pom.xml:

is there idea overcome problem?

in project use own parent pom, because defines lot of stuff regarding company.

you removed parent, lost declaration of war plugin configuration. here is:

<plugin>     <artifactid>maven-war-plugin</artifactid>     <configuration>         <failonmissingwebxml>false</failonmissingwebxml>     </configuration> </plugin>
