Troubleshooting Java, Eclipse and Maven
Git Repository - https://github.com/in28minutes/getting-started-in-5-steps

In Windows, use Windows - Preferences for Preferences.

- Things you would need to understand
- You should use a JDK with Eclipse
- [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.2:compile (default-compile) on project in28minutes-multi-module-model: Compilation failure [ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?
- (Window/Eclipse) - Preferences - Java - Installed JRE's
- You need to be connected to internet
- Maven-Error-Dependencies-Cannot-Be-Resolved - You are unable to connect to the maven repository to download the required plugins
- Configuring a Proxy
- Maven plugin uses a settings file where the configuration can be set. Its path is available in Eclipse at Window|Preferences|Maven|User Settings. If the file doesn't exist, create it and put on something like the example below
- Force download of dependencies
- ```mvn dependency:purge-local-repository```
- Delete your local repository - LAST OPTION
