Prerequisite Software
-
Install Eclipse
-
Install ragel (minimum: 6.8, recommended 6.9). For example, to install on Mac OS X via homebrew:
brew install ragel -
Install TestNG plugin in Eclipse (see below)
Build Configuration Steps
-
Checkout ohcount4j project
cd git-clone-dirgit clone https://github.com/blackducksoftware/ohcount4j.git -
Before importing the ohcount4j project into Eclipse, run the gradle build to create the generated ragel files used by the project. The gradle script supports the ability to run specifics task for cleaning, regenerating the source, and running tests. See the build.gradle file for details.
./gradlew clean build -
Create a workspace (Eclipse will require you do this when you start)
-
Install TestNG plugin
- Go to Help -> Install New Software -> Add
- Click Add
- Enter Name -> TestNG, Location -> http://beust.com/eclipse
- Click Next
- Check TestNG and follow the instructions
- Import this ohcount4j project in Eclipse
- Click File -> Import
- Choose Gradle -> Gradle Project
- Click Next
- Select root dir, e.g. git-clone-dir/ohcount4j
- Click Build Model
- In Projects: section, you should see ohlcount4j (git-clone-dir/ohcount4j) checked.
- Click Finish (do not check Copy Projects into workspace)
Project Layout
scanners - ragel scanner definitions. Because it produces Java,
name of the file should match scanner class name and it should
have net.ohloh.ohcount4j.scanner package definition on top.
Also, the extension should be .java.rl.
See ExampleScanner.java.rl.
src - source directory
test - test source directory
src/generated/java - generated scanner sources
generateScanSources target invokes ragel command on each file in scanners directory
and output goes into src/generated/java/com/blackducksoftware/ohcount4j/scan
lib - libraries
