21-26: Fix NullPointerException: null-unsafe comparison causes pipeline failure.
env.get("TEST")returnsnullwhen the variable is not set, and calling.equals()onnullthrows aNullPointerException. This is the root cause of the pipeline failure.🐛 Proposed fix using null-safe comparison
static{ try{ - if(env.get("TEST").equals("TRUE")){ + if("TRUE".equals(env.get("TEST"))){
37-41: Add null-safety checks for required environment variables before use.Line 23 has a critical null-safety issue:
env.get("TEST").equals("TRUE")will throw a NullPointerException if the TEST variable is not set (Dotenv is configured with.ignoreIfMissing(), causingget()to return null). The same problem exists on line 41 with PASSWORD—if the variable is missing, null is passed directly to.jdbcPassword(), causing an unclear Hibernate configuration error in production.Add explicit validation or use null-safe checks:
- Check if
env.get("TEST")is not null before calling.equals()- Validate that required variables like PASSWORD exist before passing to configuration, or provide clear error messages when they're missing

23-26: LGTM - Environment variable correctly configured.The
TEST: TRUEenvironment variable is properly set for the Maven build step. This aligns with the test-mode check inConnectionProvider. Note that the pipeline failure is caused by a null-safety issue in the Java code, not by this CI configuration.src/main/java/backend/ConnectionProvider.java (1)
15-17: Configuration change is appropriate but introduces null risk downstream.Using
ignoreIfMissing()is correct for CI environments where no.envfile exists. However, this meansenv.get()can returnnullfor variables not present in either the.envfile or system environment, which causes the NPE at line 23.

3-7: Remove duplicate import.
backend.entities.*is imported twice (lines 3 and 7).Proposed fix
package backend; import backend.entities.*; import io.github.cdimascio.dotenv.Dotenv; import jakarta.persistence.EntityManagerFactory; import jakarta.persistence.PersistenceConfiguration; -import backend.entities.*; import org.hibernate.jpa.HibernatePersistenceConfiguration;

15-17: Good addition ofignoreIfMissing(), but requires null-safe handling downstream.Using
ignoreIfMissing()is appropriate for CI environments. However, this meansenv.get("PASSWORD")on line 43 will returnnullwhen the.envfile is absent, which contributes to the pipeline failure.

Root cause of pipeline failure: testing flag is hardcoded and ignores the TEST environment variable.
The CI workflow sets TEST=TRUE, but this flag is hardcoded to false. The code never reads the environment variable, so the production configuration branch is always taken—even in CI—where env.get("PASSWORD") returns null (since no .env file exists), causing the NullPointerException.
Proposed fix: read from environment variable
- private static boolean testing = false;
+ private static final boolean testing = "TRUE".equalsIgnoreCase(System.getenv("TEST"));Using System.getenv("TEST") directly (rather than env.get("TEST")) ensures the CI-provided environment variable is read even when no .env file exists. The equalsIgnoreCase with the literal first avoids NPE when TEST is unset.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
