Maven Build Compilation Error : Failed To Execute Goal Org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) On Project Maven

This error message usually indicates a problem with the Maven build process. Here are some possible causes and solutions for this error:

  1. Missing or incompatible JDK: Make sure you have the correct version of Java Development Kit (JDK) installed on your system. Maven requires JDK version 1.7 or above. You can check your JDK version by running the command java -version in your command prompt or terminal. If you have multiple JDK versions installed, make sure to set the correct version in your system PATH.

  2. Incorrect or missing configuration in pom.xml: Check your project’s pom.xml file for any incorrect or missing configuration. Make sure that the <dependencies> section contains all the necessary dependencies and versions are correctly specified. Also, ensure that the <build> section includes the <plugins> section with the maven-compiler-plugin correctly configured.

  3. Compiler plugin version conflicts: There may be conflicts between the different plugins used in your Maven build. Make sure that all the plugins in your pom.xml file are compatible with each other. If you are using Maven central repository for dependencies, consider specifying versions explicitly to avoid any inconsistencies.

  4. Conflict in source and target Java versions: Maven uses the source and target configurations to compile your code. Make sure that the specified versions in your pom.xml file are compatible with your project’s code. For example, if your code is written in Java 8, you should have the following configuration in your pom.xml file:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.1</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
    </plugins>
</build>
  1. Missing or corrupt Maven dependencies: If there are issues with downloading or resolving dependencies, you might encounter compilation errors. Try running the Maven clean and install commands to clean your project and download the dependencies again. Delete the .m2 folder in your user directory if necessary, and then re-run the Maven build command.

  2. Insufficient memory allocated to Maven: If your project is large or memory-intensive, you may need to allocate more memory to Maven. You can do this by setting the MAVEN_OPTS environment variable to increase the available memory. For example, export MAVEN_OPTS="-Xmx2g" will allocate 2GB of memory to Maven.

If none of the above solutions work, provide more details about the specific error message and any additional logs to help identify the problem.
