Here is how to build the SpotBugs Eclipse Plugin:
Install Java 8
===============
Make sure you are using Java 8 or greater (since version 3.1 SpotBugs requires Java 8).
Install Eclipse
================
1) Download and install Eclipse 4.6.+ (minimum supported version).
2) Download and install EGit plugin for Git.
Choose [Help | Software Updates... | Available Software | Add Site...] and use
http://download.eclipse.org/egit/updates as update site url. Select both checkboxes
[Eclipse Git Team Provider] and [JGit]
3) Uncheck "Task focused interface" child element of "Eclipse Git Team Provider".
Uncheck "Contact all update sites..." at the bottom and click [Install..., Next..., OK].
4) Restart Eclipse.
Clone spotbugs
==============
5) mkdir ~/git
cd ~/git
git clone https://github.com/spotbugs/spotbugs.git
Setup target platform/spotbugs libraries
========================================
6) Create /home/user/bin/Eclipse46 directory. Create "plugins" link there pointing to the
"plugins" directory located in the root of Eclipse 4.6 installation. The Eclipse 4.6.3 can be fetched from
the official http://archive.eclipse.org/eclipse/downloads/ page.
7) cd ~/git/spotbugs/eclipsePlugin
echo eclipseRoot.dir=/home/user/bin/Eclipse46 > local.properties
## on Windows use this syntax instead (notice the escaped backslashes):
## echo eclipseRoot.dir=C:\\work\\eclipse-SDK-4.6\\eclipse > local.properties
cd ..
./gradlew eclipse
Import the projects
====================
8) Choose [File | Import General | Existing Projects into Workspace | Next]. The Import project import wizard opens.
9) In the wizard, proceed as follows:
a) Choose [Select root directory].
b) Enter ~/git/spotbugs. Click [Browse]. Make sure the checkbox "Search for nested projects" is selected.
c) Select all projects except the top level "spotbugs" project
d) Click [Finish].
e) Now "spotbugs" project will be compiled by Eclipse and should not have any errors,
the rest could have classpath errors due wrong target platform.
10) Set the right target platform in Eclipse. Go to
[Window | Preferences | Plugin Development | Target Platform]
and select the "Eclipse 4.6" target platform definition from the list.
Additional target platforms can be setup in the similar way.
Under Windows, replace "/home/user/" path to something like C:\Documents\%user%.
Change the code
================
11) You can immediately work with the source code. In Eclipse, make sure that
[Project | Build Automatically] is enabled (this is default). In this case, after the
first checkout both projects will be compiled. There must be NO compile errors.
Debug Eclipse from Eclipse
===========================
12) Right click eclipsePlugin project, choose [Debug As | Eclipse Application],
to start plugin debugging. You do not need to build anything, if
[Project | Build Automatically] is enabled. You can change the code during debugging
(hot code replace is supported).
Test Eclipse from Eclipse
==========================
13) Right click eclipsePlugin-junit project, choose [Debug As | JUnit Plug-In Test],
and all available SpotBugs Eclipse plugin tests will be executed. The
checked in version of tests should not fail with the checked in SpotBugs plugin code.
Build executable plug-in
=========================
14) cd ~/git/spotbugs/eclipsePlugin
./gradlew build
15) You can now watch Gradle working in the console view. After a few
seconds, the console view should print "BUILD SUCCESSFUL".
16) Right click on [eclipsePlugin] to refresh the Eclipse workspace
a) In the [eclipsePlugin]/build folder you will find the site/eclipse-daily folder which contains plugin update site.
b) Use the path to this folder in [Help | Install New Software] as the path to the update site to install it into Eclipse.
Sign plug-in (optional)
=======================
17) If you want to sign your plug-in to avoid security warning,
generate JKS file by openssl command and keytool command,
and save it as spotbugs.jks in project root directory.
About detailed process to generate JKS file, please refer the following post:
https://dev.to/kengotoda/sign-eclipse-plugin-by-gradle-4md8
18) When build, provide keystore pass via project property:
./gradlew build -P keystorepass=$YOUR_KEYSTORE_PASS
