cthing-projectversion

A version object for C Thing Software projects. This is a semantic version with additional build identification information. The additional information indicates the build type and whether the build is being performed by the C Thing Software Continuous Integration service or on a developer's machine. The following versioning scheme is used:

Build Environment	Requested Build Type	Actual Build Type	Semantic Version
CTHING_CI undefined (i.e. developer build)	snapshot	snapshot	n.n.n-0
CTHING_CI defined (i.e. CI build)	snapshot	snapshot	n.n.n-t (t = ms since Unix Epoch)
CTHING_CI undefined	release	snapshot	n.n.n-0
CTHING_CI defined	release	release	n.n.n

Usage

The library is available from Maven Central using the following Maven dependency:

<dependency>
  <groupId>org.cthing</groupId>
  <artifactId>cthing-projectversion</artifactId>
  <version>2.0.0</version>
</dependency>

or the following Gradle dependency:

implementation("org.cthing:cthing-projectversion:2.0.0")

The typical usage of this class is to set the version in Gradle build files for C Thing Software projects.

import org.cthing.projectversion.BuildType
import org.cthing.projectversion.ProjectVersion
...
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath(libs.cthingProjectVersion)
    }
}
...
version = ProjectVersion("1.2.3", BuildType.snapshot)
...

./gradlew build

The Javadoc for the library can be generated by running:

./gradlew javadoc
