## Prepare the Environment ## Prepare the Environment
There are a few preparatory tasks you should execute before, or immediately after, importing the project.
These tasks will build and index the online help, and place it somewhere accessible to Ghidra when launched from Eclipse, among other things.
This task also attempts to unpack some SDKs and/or larger dependencies required by Ghidra.
We do not provide these packages out-of-the-box because of technical and legal constraints on our distributing them.
These include the Eclipse CDT, PyDev for Eclipse, and "Yet another Java service wrapper."
If you would like to build the dependent modules, please see the relevant sections below.
For now, we will exclude the affected unpack tasks.
From the project root, execute: From the project root, execute:
```bash ```bash

Regarding `yajswDevUnpack`, please see the relevant sections on GhidraServer below.

### Get Dependencies for GhidraDev ## Run Ghidra from Eclipse
Building the GhidraDev plugin for Eclipse requires the CDT and PyDev plugins for Eclipse. To run or debug Ghidra from Eclipse, use the provided launcher.
Download `cdt-8.6.0.zip` from The Eclipse Foundation, and place it in a directory named:
`ghidra.bin/GhidraBuild/EclipsePlugins/GhidraDev/buildDependencies/`.
`ghidra.bin` must be a sibling of `ghidra`.
To respect the CDT project's resources, you will need to download the file using a browser, or at the very least, locate a suitable mirror on your own:
```bash # Building Ghidra
cd ~/Downloads # Or wherever
curl -OL http://$CHOOSE_YOUR_MIRROR/pub/eclipse/tools/cdt/releases/8.6/cdt-8.6.0.zip
mkdir -p ~/git/ghidra.bin/GhidraBuild/EclipsePlugins/GhidraDev/buildDependencies/
cp ~/Downloads/cdt-8.6.0.zip ~/git/ghidra.bin/GhidraBuild/EclipsePlugins/GhidraDev/buildDependencies/
```
Download `PyDev 6.3.1.zip` from www.pydev.org, and place it in the same directory: To build the full Ghidra distribution, you must also build the GhidraServer.
```bash ## Get Dependencies for GhidraServer
cd ~/Downloads # Or wherever
curl -OL https://sourceforge.net/projects/pydev/files/pydev/PyDev%206.3.1/PyDev%206.3.1.zip
cp ~/Downloads/'PyDev 6.3.1.zip' ~/git/ghidra.bin/GhidraBuild/EclipsePlugins/GhidraDev/buildDependencies/
```
Use Gradle to unpack the dependencies for development and building.
First, you will need to uncomment the GhidraDev project in the ```settings.gradle``` file.
Then, from your clone:
```bash
./gradlew cdtUnpack pyDevUnpack
```
### Get Dependencies for GhidraServer
Building the GhidraServer requires "Yet another Java service wrapper" (yajsw) version 12.12. Building the GhidraServer requires "Yet another Java service wrapper" (yajsw) version 12.12.

Use Gradle to unpack the dependencies.
Note that these tasks will not work until you enable the GhidraDev project in `settings.gradle`.

## Import the GhidraDev Project
If you're using BuildShip, simply refresh the Gradle project in Eclipse.
If you're not using BuildShip, re-run `gradle eclipse` and import the new project.
