-# Development of JML Parser
-
-## How To Compile Sources
-
-If you checked out the project from GitHub you can build the project with maven using:
-
-```
-mvn clean install
-```
-
-If you checkout the sources and want to view the project in an IDE, it is best to first generate some of the source
-files; otherwise you will get many compilation complaints in the IDE. (mvn clean install already does this for you.)
-
-```
-mvn javacc:javacc
-```
-
-## Extending the AST
-
-If you modify the code of the AST nodes, specifically if you add or remove fields or node classes,
-the code generators will update a lot of code for you.
-The `run_metamodel_generator.sh` script will rebuild the metamodel,
-which is used by the code generators which are run by `run_core_generators.sh`
-Make sure that `javaparser-core` at least compiles before you run these.
-
-**Note**: for Eclipse IDE follow the steps described in the
-wiki: https://github.com/javaparser/javaparser/wiki/Eclipse-Project-Setup-Guide

-# JML Parser
-
-This project provides a library for the parsing of Java with
-the Java Modelling Language (JML). JML is a formal specification
-for Java to decribe the functional behavior, e.g.,
-pre- and post-conditions of methods, class and loop invariants.
-
-The bases of this project is the [Java Parser]https://github.com/javaparser/javaparser)
-project, which is extended in the following ways:
-
-* new lexer and grammar rules
-* new AST classes and also new attributes for `Block`, `WhileStatement`,
-  `ForStatement`, `DoStatement`, and `CallableDeclaration` (constructors and methods).
-* (TODO) extension of the name resolution
-
-## JML AST Classes

-
-This project contains a set of libraries implementing a Java 1.0 - Java 15 Parser with advanced analysis
-functionalities. This includes preview features to Java 13, with Java 14 preview features work-in-progress.
-
-Our main site is at [JavaParser.org](http://javaparser.org)
-
-## Setup
-
-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](https://github.com/javaparser/javaparser-maven-sample),
-[javasymbolsolver-maven-sample](https://github.com/javaparser/javasymbolsolver-maven-sample)).
-
-Just add the following to your maven configuration or tailor to your own dependency management system.
-
-[Please refer to the Migration Guide when upgrading from 2.5.1 to 3.0.0+](https://github.com/javaparser/javaparser/wiki/Migration-Guide)
-
-**Maven**:
-
-```xml
-
-<dependency>
-	<groupId>com.github.javaparser</groupId>
-	<artifactId>javaparser-symbol-solver-core</artifactId>
-	<version>${project.version}</version>
-</dependency>
-```
-
-**Gradle**:
-
-```
-implementation 'com.github.javaparser:javaparser-symbol-solver-core:${project.version}'
-```
-
-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).
-
-Using the dependency above will add both JavaParser and JavaSymbolSolver to your project. If you only need the core
-functionality of parsing Java source code in order to traverse and manipulate the generated AST, you can reduce your
-projects boilerplate by only including JavaParser to your project:
-
-**Maven**:
-
-```xml
-
-<dependency>
-	<groupId>com.github.javaparser</groupId>
-	<artifactId>javaparser-core</artifactId>
-	<version>${project.version}</version>
-</dependency>
-```
-
-**Gradle**:
-
-```
-implementation 'com.github.javaparser:javaparser-core:${project.version}'
-```
-
-Since version 3.6.17 the AST can be serialized to JSON.
-There is a separate module for this:
-
-**Maven**:
-
-```xml
-
-<dependency>
-	<groupId>com.github.javaparser</groupId>
-	<artifactId>javaparser-core-serialization</artifactId>
-	<version>${project.version}</version>
-</dependency>
-```
-
-**Gradle**:
-
-```
-implementation 'com.github.javaparser:javaparser-core-serialization:${project.version}'
-```
-
-## How To Compile Sources
-
-If you checked out the project's source code from GitHub, you can build the project with maven using:
-
-```
-mvnw clean install
-```
-
-If you want to generate the packaged jar files from the source files, you run the following maven command:
-
-```
-mvnw package
-```
-
-**NOTE** the jar files for the two modules can be found in:
-
-- `javaparser/javaparser-core/target/javaparser-core-\<version\>.jar`
-- `javaparser-symbol-solver-core/target/javaparser-symbol-solver-core-\<version\>.jar`
-
-If you checkout the sources and want to view the project in an IDE, it is best to first generate some of the source
-files;
-otherwise you will get many compilation complaints in the IDE. (`mvnw clean install` already does this for you.)
-
-```
-mvnw javacc:javacc
-```
-
-If you modify the code of the AST nodes, specifically if you add or remove fields or node classes,
-the code generators will update a lot of code for you.
-The `run_metamodel_generator.sh` script will rebuild the metamodel,
-which is used by the code generators which are run by `run_core_generators.sh`
-Make sure that `javaparser-core` at least compiles before you run these.
-
-**Note**: for Eclipse IDE follow the steps described in the
-wiki: https://github.com/javaparser/javaparser/wiki/Eclipse-Project-Setup-Guide
