java_source
A single Java source file containing application or library code.
Backend: pants.backend.experimental.java.bsp
source
strA single file that belongs to this target.
Path is relative to the BUILD file's directory, e.g. source='example.ext'.
dependencies
Iterable[str] | NoneNoneAddresses to other targets that this target depends on, e.g. ['helloworld/subdir:lib', 'helloworld/main.py:lib', '3rdparty:reqs#django'].
This augments any dependencies inferred by Pants, such as by analyzing your imports. Use pants dependencies or pants peek on this target to get the final result.
See https://www.pantsbuild.org/2.23/docs/using-pants/key-concepts/targets-and-build-files for more about how addresses are formed, including for generated targets. You can also run pants list :: to find all addresses in your project, or pants list dir to find all addresses defined in that directory.
If the target is in the same BUILD file, you can leave off the BUILD file path, e.g. :tgt instead of helloworld/subdir:tgt. For generated first-party addresses, use ./ for the file path, e.g. ./main.py:tgt; for all other generated targets, use :tgt#generated_name.
You may exclude dependencies by prefixing with !, e.g. ['!helloworld/subdir:lib', '!./sibling.txt']. Ignores are intended for false positives with dependency inference; otherwise, simply leave off the dependency from the BUILD file.
description
str | NoneNoneA human-readable description of the target.
Use pants list --documented :: to see all targets with descriptions.
experimental_provides_types
Iterable[str] | NoneNoneSignals that the specified types should be fulfilled by these source files during dependency inference.
This allows for specific types within packages that are otherwise inferred as belonging to jvm_artifact targets to be unambiguously inferred as belonging to this first-party source.
If a given type is defined, at least one source file captured by this target must actually provide that symbol.
jdk
str | NoneNoneThe major version of the JDK that this target should be built with. If not defined, will default to [jvm].default_source_jdk.
main
str | NoneNone.-separated name of the JVM class containing the main() method to be called when executing this target. If not supplied, this will be calculated automatically, either by inspecting the existing manifest (for 3rd-party JARs), or by inspecting the classes inside the JAR, looking for a valid main method. If a value cannot be calculated automatically, you must supply a value for run to succeed.
resolve
str | NoneNoneThe resolve from [jvm].resolves to use when compiling this target.
If not defined, will default to [jvm].default_resolve.
skip_google_java_format
boolFalsepants.backend.experimental.java.lint.google_java_formatIf true, don't run Google Java Format on this target's code.
tags
Iterable[str] | NoneNoneArbitrary strings to describe a target.
For example, you may tag some test targets with 'integration_test' so that you could run pants --tag='integration_test' test :: to only run on targets with that tag.
