pom.xml (war)

pom.xml (parent)

<project xmlns="http://maven.apache.org/pom/4.0.0" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:schemalocation="http://maven.apache.org/pom/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">      <modelversion>4.0.0</modelversion>      <groupid>lu.pgd</groupid>     <artifactid>webbusiness</artifactid>     <version>0.0.1-snapshot</version>     <name>parent project</name>      <modules>         <module>../spdv_ear</module>         <module>../webbusiness</module>     </modules>      <packaging>pom</packaging> </project>

when tried run maven project parent (clean+install) got error :

[info] scanning projects... [error] [error] problems encountered while processing poms: [error] invalid packaging parent pom lu.pgd:webbusiness:0.0.1-snapshot, must "pom" "war" @ lu.pgd:webbusiness:0.0.1-snapshot, c:\dev\lu\pgd\webbusiness\0.0.1-snapshot\webbusiness-0.0.1-snapshot.pom, line 7, column 13 [error] invalid packaging parent pom lu.pgd:webbusiness:0.0.1-snapshot, must "pom" "war" @ lu.pgd:webbusiness:0.0.1-snapshot, c:\dev\lu\pgd\webbusiness\0.0.1-snapshot\webbusiness-0.0.1-snapshot.pom, line 7, column 13  @  [error] build not read 2 projects -> [help 1] [error]    [error]   project lu.pgd:ccpd-ear:0.0.1-snapshot (c:\users\x279\workspace\spdv_ear\pom.xml) has 1 error [error]     invalid packaging parent pom lu.pgd:webbusiness:0.0.1-snapshot, must "pom" "war" @ lu.pgd:webbusiness:0.0.1-snapshot, c:\dev\lu\pgd\webbusiness\0.0.1-snapshot\webbusiness-0.0.1-snapshot.pom, line 7, column 13 [error]   project lu.pgd:webbusiness-war:0.0.1-snapshot (c:\users\x279\workspace\webbusiness\pom.xml) has 1 error [error]     invalid packaging parent pom lu.pgd:webbusiness:0.0.1-snapshot, must "pom" "war" @ lu.pgd:webbusiness:0.0.1-snapshot, c:\dev\lu\pgd\webbusiness\0.0.1-snapshot\webbusiness-0.0.1-snapshot.pom, line 7, column 13

could me here understand going wrong here please ?

usually folder structure multi-module project this:

- parent-project-folder   - pom.xml (parent-project)   - submodule-project-folder     - pom.xml (submodule-project)   - another-submodule-project-folder     - pom.xml (another-submodule-project)

then parent definition have fine, have parent project next submodules, need configure bit more.

try adding relativepath parent specifications:

<parent>    <groupid>...    ...    <relativepath>path/to/your/parent/pom.xml</relativepath> </parent>
