Hi,
I am using the library in a maven plugin.
burningwave version core 12.62.7.

I am trying to compile a class and I get the following error

Weirdly I have the classes in my classpath (maven dependencies) and I could generate the source class without issue.
But the compilation fails.
To solve the error, I had to add the classpaths of the project wherein I want to store the compiled class. like this:

var compilationTask = javaMemoryCompiler.compile(
                JavaMemoryCompiler.Compilation.Config.forUnitSourceGenerator(
                                unitSG
                        )
                        .addClassPaths(runtimeClasspathElements)
                        .storeCompiledClassesTo(
                                sourcePath.toAbsolutePath().toString()
                        )
        );
        compilationT…

Hello! The jar that contains the package javax.inject is not in the classpath of your application. You can solve by adding the jar to the classpath or by adding it at runtime as is shown in this example

thanks, How do I add a class from the dependencies of my application ? the only option is to give a path to the jar containing that class ?

By the way the javax.inject is already in my classpath since I can generate the source files, but the compilation fails

You can add the classpath when you launch the java command by adding the jar to -cp parameter or manually by using the method addClassRepository (it possible to add folder, .zip, .jar, .ear, .war, .jmod or .class files):

ClassFactory.ClassRetriever` classRetriever = componentSupplier.getClassFactory().loadOrBuildAndDefine(
	LoadOrBuildAndDefineConfig.forUnitSourceGenerator(unitSG)
	//With this we are adding an external path where to search classes needed for class compilation and loading.
	//It possible to add folder, .zip, .jar, .ear, .war, .jmod or .class files
	//The difference between this method and .setClassRepository is that the method .addClassRepository will add
	//paths to the configured defaults paths, instead the method .setClassRepository will replace the configured
	//defaults paths and the subsequent calls to method .addClassRepository will add paths to the replacement paths
	.addClassRepository(
		pathHelper.getAbsolutePathOfResource("../../src/test/external-resources/libs-for-test.zip")
	)
);

However, I advise you to carefully read all the documentation relating to the runtime compilation module:

... I noticed that the class javax.inject.Provider is not present in the JDK that you are using (11). I think that is a deprecated class that has been removed since JDK 8

                        )
        );
        compilationTask.join();

runtimeClasspathElements here is the list of classpath elements of the project where I want to store the compiled class, not the project that runs the code above.

Thanks for the help !
