I am using Eclipse 2023 to build a Typescript module with node/npm. I like there to execute each time the a "*.ts" file changes the maven exec plugin to do the typescript compilation.
I have added the exec-maven-plugin
and as well the lifecycle-mapping
plugin. But when I change the "*.ts" file or calling "build" on my maven project, then the plugin get not automatically executed. I need each time to run the maven build manually by using a "Run Configuration".
The project in Eclipse is a maven project (has the "M" icon) and as well under Builders the "Maven Project Builder set.
Any hint what I am doing wrong or what I missed?

Eclipse usually uses his embedded copy of Maven. The m2.conf
is generated dynamically by eclipse on demand (in example: /home/yourname/workspace/.metadata/.plugins/org.eclipse.m2e.launching/launches/m2conf17481979518454286727.tmp
).
You need to install maven separatly in order to do a automatic build using a builder in the project.
Ok, first you need to activate automatic builds:
Then open the project-properties and add a builder
Choose the mvn-executable and adjust the properties and goals according to your project.
