Get values from properties file using Groovy
It looks to me you complicate things too much.
Here's a simple example that should do the job:
For given test.properties
file:
a=1
b=2
This code runs fine:
Properties properties = new Properties()
File propertiesFile = new File('test.properties')
propertiesFile.withInputStream {
properties.load(it)
}
def runtimeString = 'a'
assert properties."$runtimeString" == '1'
assert properties.b == '2'
Had a similar problem, we solved it with:
def content = readFile 'gradle.properties'
Properties properties = new Properties()
InputStream is = new ByteArrayInputStream(content.getBytes());
properties.load(is)
def runtimeString = 'SERVICE_VERSION_MINOR'
echo properties."$runtimeString"
SERVICE_VERSION_MINOR = properties."$runtimeString"
echo SERVICE_VERSION_MINOR
Unless File
is necessary, and if the file to be loaded is in src/main/resources
or src/test/resources
folder or in classpath, getResource()
is another way to solve it.
eg.
def properties = new Properties()
//both leading / and no / is fine
this.getClass().getResource( '/application.properties' ).withInputStream {
properties.load(it)
}
//then: "access the properties"
properties."my.key"
Just in case...
If a property key contains dot (.) then remember to put the key in quotes.
properties file:
a.x = 1
groovy:
Properties properties ...
println properties."a.x"
