How to configure toolchains plugin in m2e / Installed maven in Eclipse

Question

Currently i am using maven(Apache Maven 3.3.9) & Java(Java version: 1.8.0_91) installed in my windows machine. I have a java application which was developed using Java Version 1.6.0_31.

Since Apache maven(3.3.9) is not directly compatible with the previous version of Java(Prior to 1.8) I have included toolchains plugin to compile and run the project with Java 1.6. I can do a successful build using command prompt.

But when I try to build the same project using eclipse with eclipse m2e plugin or by adding the external maven(3.3.9) using eclipse->Windows->Preferences->Maven->Installations, I am getting the below error.

Note: With Java_1.8 I can build the project successfully without toolchains plugin. But with toolchains plugin configured I am facing this issues. Can anyone help me to resolve this.

The required toolchains.xml is present in both maven config folder as well as in the .m2 folder of the repository

UPDATE: Maven compiler plugin configuration:

Answer 1

The resolved after changing goals in eclipse run configuration as below.

The problem is eclipse is not automatically reading the toolchains.xml. We have to manually specify in the goals. I fixed this by referring the this Link
