Maven Build Fail in Eclipse (Tests and Plugin)

Question

I am using Maven Buildin Eclipse IDE for a Spring project for uploading files.SPRING. The error is arising from

1-Plugin. I deleted the maven-compiler plugin from /.m2 directory (Windows), but the error still exist. The usual consensus is to delete whole ./m2 directory which is not feasible as I have other projects.

2- The FileUploadTest.java seems to be giving out a lot of errors. Is this due to corrupted jars or error in my pom.xml file?

Answer 1

In Maven, test classes have not to be located in the src/main/java directory but in the src/test/java directory.
src/test/java is indeed the test source directory and only classes located here can use dependencies specified with the test scope.

So all your test classes using classes of this dependency cannot compile :

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

Move your test classes in src/test/java and it should solve a large part of your issue.

This introduction on the directory layout of Maven could probably help you.
