org.jetbrains. jps.builders.impl.java.JavaoCmpilerTool available

I want to dynamically compile a piece of Java code, but ToolProvider. getSystemJavaCompiler() returns null,

Perhaps the idea is a JRE environment, but I found the class org.jetbrains. jps.builders.impl.java.JavaoCmpilerTool , which allows me to create a java.tools.JavaCompiler  using 'create.Compiler ';


Why can Class. forName ("com. sun. tools. javac. api. JavacTool") be loaded

 

Is this class safe for users?

Is it safe to use org. jetbrains. jps. builders. impl. java. JavaoCmpilerTool? Is it possible for it to return null?

According to https://plugins.jetbrains.com/docs/intellij/explore-api.html#26-refrain-from-using-internal-classes, you should refrain from using classes from an impl package.

If you use it, please keep in mind it can be changed in the future in a backward incompatible way. The method is annotated with @NotNull, which indicates that it can't return null.

I don't understand. IDEA should be running in a JRE environment, so why does executing Class.forName("com.sun.tools.javac.api.JavacTool") not throw an exception?

I'm sorry, but I'm confused by your questions.

You asked whether it is safe to use org.jetbrains.jps.builders.impl.java.JavacCompilerTool and I answered it is not. What is unclear here?

I don't understand what problem you have with com.sun.tools.javac.api.JavacTool. You write that it can be loaded:

Why can Class. forName ("com. sun. tools. javac. api. JavacTool") be loaded

 and doesn't throw an exception:

why does executing Class.forName("com.sun.tools.javac.api.JavacTool") not throw an exception?

Why does this cause a problem?
