This is the current Github for JDK 11 and works fine. I have migrated my project to JDK 17. It works fine locally but breaks in Github workflows. I don't know how can I fix it?

You are using Maven compiler plugin version 3.8.1, which was released in May 2019 for Java 17, which was released in September 2021. Make sure that you use the newest Maven Compiler plugin and that you specify the correct Java release in its configuration setting in pom.xml.
<project>
[...]
<properties>
<maven.compiler.release>17</maven.compiler.source>
</properties>
[...]
</project>
Or like this:
<project>
[...]
<build>
[...]
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.10.1</version>
<configuration>
<release>17</source>
</configuration>
</plugin>
</plugins>
[...]
</build>
[...]
</project>
Source: https://maven.apache.org/plugins/maven-compiler-plugin/examples/set-compiler-source-and-target.html
You also don't specify the Java version in your workflow, the GitHub actions Maven starter workflow specifies it like this:
name: Java CI
on: [push]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- name: Set up JDK 17
uses: actions/setup-java@v3
with:
java-version: '17'
distribution: 'adopt'
- name: Build with Maven
run: mvn --batch-mode --update-snapshots package
Otherwise you are using whatever Java version is the default in the GitHub runner you are using and as you are not pinning down the version but instead use ubuntu:latest, this may not be the one you want and even change over time.
