'build.plugins.plugin.version' for org.apache.maven.plugins:maven-clean-plugin is missing.

[Roberto JR]

Compiling with Netbeans, the warning 

"'build.plugins.plugin.version' for org.apache.maven.plugins:maven-clean-plugin is missing. @ line 121, column 21"

can be fixed replacing 

            <plugin>

                <artifactId>maven-clean-plugin</artifactId>

                <configuration>

                    <filesets>

                        <fileset>

                            <directory>overlays</directory>

                        </fileset>

                    </filesets>

                </configuration>

            </plugin>

in pom.xml

with

<plugin>

        <artifactId>maven-clean-plugin</artifactId>

        <version>3.0.0</version>

        <executions>

          <execution>

            <id>auto-clean</id>

            <phase>initialize</phase>

            <goals>

              <goal>clean</goal>

            </goals>

          </execution>

        </executions>

      </plugin>

Hi,

What version of NetBeans are you using? Do you know what version of Maven it includes?

Replacing the current maven-clean-plugin configuration with the proposed section is not the right way to resolve this - the configuration exists specifically to remove “temporary” files that otherwise would be left, and the replacement wouldn’t do this.

But I would like to look into why this is causing a problem in NetBeans - I haven’t seen the same problems occur from the command line.

Regards,

G

Hello,

Thanks for answer.

Netbeans -> 8.1. The maven version is - >3.3.9.
I think that this solution is not the right way indeed, but worked and I could install the version 1.9-rc1 and test from NetBeans.
This issue does not occur from the command line.

Thanks again!

After temporarily try to "fix" the above problem, this now occured:

'build.plugins.plugin.version' for org.apache.maven.plugins:maven-clean-plugin is missing. @ line 120, column 21

<dependency>

 <groupId>org.vivoweb</groupId>

 <artifactId>vivo-webapp</artifactId>

 <version>${vitro-version}</version> <<<<<<<

 <type>war</type>

</dependency>

These problems DO occur with the command line (appears at the beginning, so I did not notice)
