In order to configure Jeta you need to create jeta.properties file in the root package of the source set. It’s a plain Java Properties file with key=value format.
Unfortunately, there’s no way of knowning where the source directory is located, so you must provide it by yourself. There are two ways to achieve this. First one is to declare sourcepath option in your build.gradle:
build.gradle
compileJava {
options.sourcepath = files('src/main/java')
}
The second way is available using apt arguments. Note that you need a plugin that supports this feature. If not, there are some hacks that might help, so you should google it. If your plugin allows, add next snippet into the build.gradle file:
apt {
arguments {
jetaProperties "$project.projectDir/src/main/java/jeta.properties"
}
}
jeta.properties
Let’s go through the options available to controll code generating. As previously mentioned, the most required property is metasitory.package. It must be unique for any module, e.g. test module. You will need this package to provide to MapMetasitory constructor at runtime to use this metasitory. The other options are described below as comments:
# Source directory path. Absolute or relative to `jeta.properties` path
# to the source folder. Define it in case `jeta.properties` isn't in the root
# of the source set. (`.` by default)
sourcepath=.
# Unique per module java package, where metasitory will be stored.
# (`` by default, recommended to define)
metasitory.package=com.example
# Set this option to `true` to skip code re-generating in case the master's source code
# hasn't been changed since the previous run. Boost up code processing.
# (`false` by default)
utd.enable=true
# Delete metacode if its master does not exists anymore
# (`true` by default if `utd` feature's enabled)
utd.cleanup=true
# Absolute or relative to `jeta.properties` path, where `utd` data is stored
# ('java.io.tmpdir' by default, recommended to define)
utd.dir=../../../build/jeta-utd-files
# Output debug information (false by default)
debug=true
# Output the time metacode built in (true by default)
debug.built_time=true
# Output `utd` statuses:
# `+` - metacode created or rewritten
# `-` - metacode removed (if `utd.cleanup` enabled)
# `*` - master is up-to-date
# (`true` by default if `debug` and `utd` are enabled)
debug.utd_states=true
# Custome annotation processors (comma separated)
# go to http://jeta.brooth.org/guide/custom-processor
processors.add=com.example.apt.MyCustomProcessor
# Disable a processor by its annotation (comma separated, reg-exp allowed)
processors.disable=^Meta.*$,^Log$
# Metacode file header
file.comment=\n Use is subject to license terms. \n
# Default scope for dependency injection
# go to http://jeta.brooth.org/guide/inject
inject.scope.default = org.brooth.jeta.tests.inject.DefaultScope
# org.brooth.jeta.inject.Inject annotation alias.
inject.alias=javax.inject.Inject
# org.brooth.jeta.Provider alias
inject.alias.provider=javax.inject.Provider
# Custom metasitory writer

metasitory.writer=org.brooth.jeta.apt.EchoMetasitoryWriter
