How do I specify a quartz property file outside of the classpath in gradle?

I'm attempting to specify my quartz properties file in gradle. From a 'config' directory rather than from resources.

String quartzProperties = System.properties['org.quartz.properties'] ?: "file:config/local/quartz.properties"
System.setProperty("org.quartz.properties", quartzProperties)

The output from

(System.properties).each {
    println "Prop ${it}"
}

or the properties task, is

Prop quartz.properties=file:config/local/quartz.properties

The output from quartz is

PropertiesFactoryBean      --- Loading properties file from class path resource [quartz.properties]
SchedulerConfig$$EnhancerB --- Cannot load quartz.properties.

The symptom of it not being set is that I am getting the wrong sql dialect so the application gives a database error on load.

Solution

I had the same question and looking at your code, using file:config/local/quartz.properties was wrong most likely. The official docs really only put a path into that property, without any URI-prefix or whatsoever. That prefix most likely made the path invalid and Quartz was unable to find it. The following is an example from GitHub:

workdir=`dirname $0`
workdir=`cd ${workdir} && pwd`
QUARTZ=${workdir}/../..
[...]
# Set the name and location of the quartz.properties file
QUARTZ_PROPS="-Dorg.quartz.properties=${workdir}/quartz.properties"

At least one available factory really only uses a file as well:

    String requestedFile = System.getProperty(PROPERTIES_FILE);
    String propFileName = requestedFile != null ? requestedFile
            : "quartz.properties";
    File propFile = new File(propFileName);

Besides that, at least nowadays some factories exist which support providing settings directly:

StdSchedulerFactory(Properties props)
Create a StdSchedulerFactory that has been initialized via initialize(Properties).

initialize(InputStream propertiesStream)
Initialize the SchedulerFactory with the contents of the Properties file opened with the given InputStream.
