After a bit more digging, I found that it is pretty easy to modify the IDE's classpath itself.

All you need to do is to drop a dependency into Intellij installation directory's lib subfolder, and reference the jar inside classpath.txt.

Initially, I added the jars my GDSL depends on directly, but then I realized I could simply add a dependency on Apache Ivy to classpath.txt instead and @Grab annotations would start working.

maven-checkstyle-plugin failed to parse Java 'record'

I'm trying to setup checkstyle in our project - but seems like Maven (v3.8.3) or maven-checkstyle-plugin (v3.1.1) itself are not aware of Java 14's record (we use Java 17).

The plugin by default comes with Checkstyle version 8.29. Try explicitly defining the CheckStyle version (plus a small version bump to 3.1.2). For example, with version 9.2:

ANSWER

Answered 2022-Jan-10 at 10:46

It is unfortunately not possible to distinguish between the name of a top-level class and the name of a nested class from only the qualified name, or by analysing only a single source file. At least not in all cases.

To make that distinction you have to perform a resolution step, to find out what the names reference. This necessarily involves multiple source files.

The resolution step probably involves looking at the information in the AST or the class files of the referenced elements.

Note: Even if the resolution step involves multiple source files that information is still static information.

QUESTION

ClassOrInterfaceDeclaration.getTokenRange() gets all the tokens for a file even after removing nodes from the class

Asked 2021-Dec-30 at 04:35

When I remove "ClassOrInterfaceDeclaration" nodes from a class in CompilationUnit (JavaParser) from a parsed file that contains more than one class, ClassOrInterfaceDeclaration.getTokenRange() gets all the tokens even the removed nodes tokens. For example, the code snippet at positions 1 and 2 will give the same result, although I already removed nodes from ClassOrInterfaceDeclaration n.

Does anyone know how to get the correct tokens list?

ANSWER

Answered 2021-Dec-30 at 04:35

Ater Adjusting the file that contains the node, you must update the source root by using method saveAll, to override the AST to your file, like that

JavaParser- Removing an operator from the expression at the AST level. How to replace a parent node with its child?

Asked 2021-Aug-21 at 11:53

I am doing some work on mutation testing at the Abstract Syntax Tree level. So far, I have dealt with Operator Replacement mutations, which were fairly easy to implement using the JavaParser library (https://github.com/javaparser/javaparser). Below is the simple, example code that I am parsing into the AST and trying to perform mutations on it. I know the if statement does not make sense but it is not the point here:

public class Example {

According to the documentation of ModifierVisitor:

This visitor can be used to save time when some specific nodes needs to be changed. To do that just extend this class and override the methods from the nodes who needs to be changed, returning the changed node. Returning null will remove the node.

In your case, if a node that should be replaced is found, the "changed node" would be the left/right node, so you should return those accordingly.

n.replace(leftChild) is working correctly. You just need to return the new node that is in its place, which you probably didn't do.

Here's an example:

ANSWER

Answered 2021-Jul-31 at 10:30

Thread pools won't work with ANTLR4. For performance reasons there's no extra thread handling, except for one place where the shared DFA is accessed by a parser or lexer.

So, the only way you can use threads is to associate a lexer/parser instance to a thread and access that only from this single thread. Use a dedicated thread per parser instance and never share lexers/parser between threads.

Install javaparser

The project binaries are available in Maven Central. We strongly advise users to adopt Maven, Gradle or another build system for their projects. If you are not familiar with them we suggest taking a look at the maven quickstart projects (javaparser-maven-sample, javasymbolsolver-maven-sample). Just add the following to your maven configuration or tailor to your own dependency management system. Since Version 3.5.10, the JavaParser project includes the JavaSymbolSolver. While JavaParser generates an Abstract Syntax Tree, JavaSymbolSolver analyzes that AST and is able to find the relation between an element and its declaration (e.g. for a variable name it could be a parameter of a method, providing information about its type, position in the AST, ect).
