## README

# About nb-javac!
"nb-javac" is a patched version of OpenJDK "javac", i.e., the Java compiler. This has long been part of NetBeans, providing a highly tuned Java compiler specifically for the Java editor i.e., parsing and lexing for features such as syntax coloring, code completion.

## Prerequisite
  - Git
  - Ant 1.9.9 or above
  - JDK 8 or above (to build nb-javac)
  - Apache Maven

## Building nb-javac jar files
1. Obtain the code with the following command

```
$ git clone https://github.com/oracle/nb-javac.git
```

2. To get a specific version use the following command

```bash
$ git checkout <release_tag_name> 
```

3. Run the below command to build nb-javac.

```bash
$ ant -f ./make/langtools/netbeans/nb-javac clean jar
```

Two jars namely `javac-api*.jar` and `javac-impl*.jar` are going to appear
at location `./make/langtools/netbeans/nb-javac/dist/`

4. Run below command to zip the source code of nb-javac

```bash
$ ant -f ./make/langtools/netbeans/nb-javac zip-nb-javac-sources
```

## Publishing to maven central / OSSRH

1. Aquire an account for OSSRH from sonatype and get access to the target groupId
   See here: https://central.sonatype.org/pages/ossrh-guide.html

2. Configure the maven installation so that the credentials are made available
   for the server with the id oss.sonatype.org

3. Run
   ```
   ant -f ./make/langtools/netbeans/nb-javac publish-to-ossrh-snapshots -Dmaven.groupId=your.grp.id
   ```
   to publish snapshot artifacts (https://oss.sonatype.org/content/repositories/snapshots/)

4. Run
   ```
   ant -f ./make/langtools/netbeans/nb-javac publish-to-maven-central -Dmaven.groupId=your.grp.id
   ```
   to stage the release, which will get promoted to maven central, after it has
   been manually released.

## Installation

#### 1. Copy jars by following commands

```bash
cp nb-javac/make/langtools/netbeans/nb-javac/dist/nb-javac-$ver-api.jar netbeans/java/libs.javacapi/external/nb-javac-$ver-api.jar
cp nb-javac/make/langtools/netbeans/nb-javac/dist/nb-javac-$ver-impl.jar netbeans/java/libs.javacimpl/external/nb-javac-$ver-impl.jar
```

#### 2. Open Netbeans and activate Java SE by creating or opening a ant, maven or gradle then copy jars by these commands

```bash
cp nb-javac/make/langtools/netbeans/nb-javac/dist/nb-javac-$ver-impl.jar netbeans/nbbuild/testuserdir/modules/ext/nb-javac-$ver-impl.jar
cp nb-javac/make/langtools/netbeans/nb-javac/dist/nb-javac-$ver-api.jar netbeans/nbbuild/testuserdir/modules/ext/nb-javac-$ver-api.jar
