Adding a *.jar file (originating from java-wrapped C++ code) to an SBT project classpath
I thought using unmanaged dependencies in SBT projects was simply dropping a jar file
into the lib directory, until I bought an SDK for a biometric device.
Both the C++ and the Java packages were provided. I opted for the Java package, copying the provided jar file and the JNI (*.so) files into the appropriate locations and configuring the ja
/** * In my <code>build.sbt</code> file, I appended a blank line and then the following: */ libraryDependencies += "groupID" % "artifactId" % "revision" from "file:///home/Danogbuagu/Projects/biometric-lib/filename.jar" // where, // groupID for example is like: com.zigzagcompany // artifactId for example is like: zigzag // revision for example is like: 1.3.4 // Remember the line befor the code and that after.
// Assuming the following Person class and companion object:
class Person extends MongoRecord[Person] with ObjectIdPk[Person] {
def meta = Person
object surname extends StringField(this, 40)
object firstName extends StringField(this, 40)
object otherNames extends StringField(this, 40) {
override def optional_? = true

val nameKeys = (surname.name -> 1) ~ (firstName.name -> 1)
createIndex(nameKeys, unique = true)
}
