% IDE support in the JDK
|
||
|
|
|
||
|
|
## Introduction
|
||
|
|
|
||
|
|
When you are familiar with building and testing the JDK, you may want to
|
||
|
|
configure an IDE to work with the source code. The instructions differ a bit
|
||
|
|
depending on whether you are interested in working with the native (C/C++) or
|
||
|
|
the Java code.
|
||
|
|
|
||
|
|
### IDE support for native code
|
||
|
|
|
||
|
|
There are a few ways to generate IDE configuration for the native sources,
|
||
|
|
depending on which IDE to use.
|
||
|
|
|
||
|
|
#### Visual Studio Code
|
||
|
|
|
||
|
|
The make system can generate a [Visual Studio Code](https://code.visualstudio.com)
|
||
|
|
workspace that has C/C++ source indexing configured correctly, as well as
|
||
|
|
launcher targets for tests and the Java launcher. After configuring, a workspace
|
||
|
|
for the configuration can be generated using:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
make vscode-project
|
||
|
|
```
|
||
|
|
|
||
|
|
This creates a file called `jdk.code-workspace` in the build output folder. The
|
||
|
|
full location will be printed after the workspace has been generated. To use it,
|
||
|
|
choose `File -> Open Workspace...` in Visual Studio Code.
|
||
|
|
|
||
|
|
##### Alternative indexers
|
||
|
|
|
||
|
|
The main `vscode-project` target configures the default C++ support in Visual
|
||
|
|
Studio Code. There are also other source indexers that can be installed, that
|
||
|
|
may provide additional features. It's currently possible to generate
|
||
|
|
configuration for two such indexers, [clangd](https://clang.llvm.org/extra/clangd/)
|
||
|
|
and [rtags](https://github.com/Andersbakken/rtags). These can be configured by
|
||
|
|
appending the name of the indexer to the make target, such as:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
make vscode-project-clangd
|
||
|
|
```
|
||
|
|
|
||
|
|
Additional instructions for configuring the given indexer will be displayed
|
||
|
|
after the workspace has been generated.
|
||
|
|
|
||
|
|
#### Visual Studio
|
||
|
|
|
||
|
|
This section is a work in progress.
|
||
|
|
|
||
|
|
```shell
|
||
|
|
make ide-project
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Compilation Database
|
||
|
|
|
||
|
|
The make system can generate generic native code indexing support in the form of
|
||
|
|
a [Compilation Database](https://clang.llvm.org/docs/JSONCompilationDatabase.html)
|
||
|
|
that can be used by many different IDEs and source code indexers.
|
||
|
|
|
||
|
|
```shell
|
||
|
|
make compile-commands
|
||
|
|
```
|
||
|
|
|
||
|
|
It's also possible to generate the Compilation Database for the HotSpot source
|
||
|
|
code only, which is a bit faster as it includes less information.
|
||
|
|
|
||
|
|
```shell
|
||
|
|
make compile-commands-hotspot
|
||
|
|
```
|
||
|
|
|
||
|
|
### IDE support for Java code
