I have a Maven project already well structured. I want to create the . jar to run the application.
Inside the project, at the prompt, I did:
mvn clean install package
Returns the error:
C: exampleSpring portal-de-inscription portal-api>mvn package

It looks like an error with the Java version, or JAVA_HOME might not be set for the current session. Try before running the above command, check the Java version. If everything is OK, inside the POM check the target version of the project, in the Maven-build-plugin. If not, post your POM.

@Celso Marigo Jr The measured line could not be found. I found the following: <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <start-class>com.dendetech.application.Application</start-class> <java.version>1.8</java.version> </properties> <build> The version I use is 7. Here’s how 8. This project was cloned from gitbucket. I’ll change the version and post anything.

It looks like you have configured in pom to compile in version 8 and you do not have version 8 of Java. Put your pom.xml there please. Take advantage of and run java -version on the terminal as well.

Ba version of java here is 7. I can change in this file the version, or going in the property of the project and changing to the correct version and in the build recognize java?
– André Nascimento
Andre in your pom. is specified to compile your project with Java 8, and your Java is 7. I advise you to do the following, if you do not have any code that compiles only in Java 8 exchange in your pom the <java.version> to 1.7 or change your JAVA_HOME to point to a Java 8. If you go in the project property and switch to Java 7 for example, when you build the project it will change to 8 again as your pom.xml.
