Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile)

Question

I know this is a duplicate question but the answers on other topics didn't help me.

I'm using Eclipse Photon, Java Version :10, I've set jdk/jre versions on 10 in eclipse and pom.xml file. I've changed eclipse.ini file :

-Dosgi.requiredJavaVersion=10 (it was set to 1.8)

and also I've added plugin in my pom.xml :

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.8.0</version>
                <configuration>
                    <source>10</source>
                    <target>10</target>
                </configuration>
            </plugin>

Nothing helped. This is my pom.xml :

The dependencies aren't being read in class files and also I've tried deleting .m2 repository and starting Eclipse and doing the : Maven->Clean, Maven->install, and than Maven->update project. Nothing helped. I'm really stuck here for about 2-3 hours now.

Note: in Windows->Preferences->installed JRE's the jre10 was marked with the tick. I changed it to mark the jdk10. but still error :

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project spring-security-demo-06-user-roles: Compilation failure

Everything was working fine until I added the dependency of : spring-security-taglibs.

Deleting the dependency doesn't do anything aswell.

Solution

Check properly settings with version of your project in eclipse and version of your runner for maven.

I have reproduced the same issue with maven-compiler plugin, but using version 3.8.1:

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project testName: Fatal error compiling

My POM was:

 <plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-compiler-plugin</artifactId>
   <configuration>
      <source>11</source>
      <target>11</target>
      </configuration>
  </plugin>

To clarify:

in project I'm using Java 11 and IntelijIDEA (but logic I think the same for eclipse). So I'm using maven lifecycle phases fine only if my version of project (check properly Project Structure -> Project Settings) corresponds to version of maven runner.

E.g. if version of runner is for java 8, but project settings are for Java 11 then I'm getting this error. If I have the same for both then I don't have any problems.

---

And I highly recommend to check all settings for maven and the whole project. It helps to avoid the issues in the future. Deleting folder for maven is as alternative solution, but it must be last thing that you need to do.
