Unable to use module com.azure.identity in modular java project

I am trying to use Microsoft's azure-identity module) in a Gradle app.

However .\gradlew run fails with this stack trace:

> Task :run
java.lang.module.FindException: Module msal4j.persistence.extension not found

> Task :run FAILED

FAILURE: Build failed with an exception.

I tried adding msal4j.persistence.extension as a dependency in my build.gradle.kts and my module-info.java as recommended below, but then I get this error

> Task :compileJava FAILED
...\test\src\main\java\module-info.java:4: error: module not found: msal4j.persistence.extension
    requires msal4j.persistence.extension;
                               ^
1 error

It seems that msal4j.persistence.extension being an automatic module may have something to do with this?

build.gradle.kts

plugins {
    id("java")
    id("application")
}

group = "com.example"
version = "0.1"

repositories {
    mavenCentral()
}

dependencies {
    implementation(platform("com.azure:azure-sdk-bom:1.2.28"))
    implementation("com.azure:azure-identity")
    implementation("com.azure:azure-core")

    implementation("com.microsoft.azure:msal4j-persistence-extension:1.3.0")
}

application {
    mainClass = "com.example.Main"
    mainModule = "com.example"
}

src/main/java/module-info.java

module com.example {
    requires java.base;
    requires com.azure.identity;

    requires msal4j.persistence.extension; // *

    exports com.example;
}

Relevant gradle dependencies

java.lang.module.FindException: Module msal4j.persistence.extension not found.

The msal4j.persistence.extension library is not a true JPMS module, which means it can’t be directly included with a requires statement in module-info.java.

  • Java’s module system does not recognize it because it's packaged as a regular JAR, not as a fully modular JAR.

msal4j.persistence.extension dependency is not strictly necessary at compile-time, try marking it as a requires static dependency in module-info.java.

module com.example {
    requires java.base;
    requires com.azure.identity;
    requires static msal4j.persistence.extension;

    exports com.example;
}
  • Use --add-reads or --add-exports JVM Options at Runtime
./gradlew run --args="--add-reads com.example=msal4j.persistence.extension"

After above changes application successfully authenticates using Azure Identity via DefaultAzureCredential.

Build status:

enter image description here Gradle console:
