Run Spring project

  • 772

For each modification in spring I do the following:

mvn clean package

that instruction takes 1 min (which is a lot)

then I run the jar that was packed in the target folder

java -jar nombreDelJar.jar

Do I have to execute these instructions every time I make changes? Is there no other way that is faster?

    mvn clean package

    it is

    mvn clean

    followed by

    mvn package

    As its name suggests, cleanit deletes all classes generated in the build (basically the target) directory.

    packagedoes all the steps from compilation to packaging. If a module has not been modified, it does not recompile it.

    Doing cleanit forces you to recompile the entire project, while doing mvn packageit alone will only recompile the affected modules.

    Whether that makes the process faster will depend on how you have structured the program in modules.

    UPDATE: If what you want is to run from Maven, it is not a default functionality but there is a plugin for that:

    <plugin>
   <groupId>org.codehaus.mojo</groupId>
   <artifactId>exec-maven-plugin</artifactId>
   <version>1.4.0</version>
   <configuration>
       <mainClass>es.x-rw.Main</mainClass>
   </configuration>
 </plugin>

    (inside build->plugins)

    Unfortunately, it doesn't seem that the official website ( https://www.mojohaus.org/exec-maven-plugin/ ) is up (although it's still a problem with my corporate connection) so I can't give the exact configuration.

    So you can do:

    mvn package exec:exec

    To make the package first and then execute the plugin goal exec `exec.

    If you want everything to run as part of the maven lifecycle, you'll need to associate the plugin with a lifecycle stage using the <execution>; for example you can see it in Spanish or in English but better explained .

    And if all that fails, you can always do a .bat or a .sh :-p

  2. Try mvn spring-boot:runto run the application.

  3. Every time you need to create the Jar you must execute those commands,

    I leave you the following command that will take less time, since it does not execute the tests or does not look for them to exist

    mvn clean install -Dmaven.test.skip=true

    Cheers
