Maven build Compilation error : Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project Maven

Question

I have a maven project forked and cloned from a git repo onto my eclipse. It is build on Java 8. The first thing i do is perform a

mvn clean install


        

Answer 1

Doing this in pom.xml file and after updating the project, the problem is gone.

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.4</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
</configuration>
</plugin>

1. Update the pom.xml under <plugin></plugin>.

2. Update your project.

3. Then clean maven and install maven.

Answer 2

In my case, it was caused from an incompatibility with OpenJDK 9 (which I haven't investigated).

If you don't need JDK 9, a temporary work-around would be to purge it from your machine:

sudo apt-get remove --purge openjdk-9-jdk openjdk-9-jre 
sudo apt-get remove --purge openjdk-9-jdk-headless openjdk-9-jre-headless

Buddy,
If every this is up-to-date, even then you are having this problem, then
try running this command from the terminal directly instead of running from eclipse.
$ mvn clean install

and make sure these things:

• maven is in system path
• all maven dependencies are avaialble at `.m2/repository`
• java is in system path

Answer 5

The below pom.xml configuration is making the build successful and make sure project buildpath JRE System library should point to Java8.

org.apache.maven.pluginsmaven-compiler-plugin3.7.0 1.81.8

Answer 6

Worked by adding this in pom.xml:

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
</properties>

Even you have SDK 13 or 14.
