using eclipse showing error plugin execution not covered by lifecycle configuration:

[JakeCham]

Hi Team,

I'm encountering "plugin execution not covered by lifecycle configuration:org.apache.maven-toolchain-plugin:1.1 toolchain(execution: default, phase: validate)" while on eclipse ...

Any idea how to resolve this ? tried to maven-> update but issue is still there 

Thanks in advance!

Hi @JakeCham ,

The error might be coming from any update in pom.xml file. Can you try to add maven life cycle plugin and then include the metadata information in that:

I believe using a recent version of Eclipse will not show that warning any more.

In release v2.6.0 (21th February 2024) of m2e-core "the `maven-toolchains-plugin` is now disabled by default for workspace builds."
