jvm_war

A JSR 154 "web application archive" (or "war") with first-party and third-party code bundled for deploys in Java Servlet containers.

Backend: pants.backend.experimental.java

tags​

field.type_hint
required

Arbitrary strings to describe a target.

For example, you may tag some test targets with 'integration_test' so that you could run scie-pants-linux-x86_64 --tag='integration_test' test :: to only run on targets with that tag.

description​

field.type_hint
required

A human-readable description of the target.

Use scie-pants-linux-x86_64 list --documented :: to see all targets with descriptions.

resolve​

field.type_hint
required

The resolve from [jvm].resolves to use when compiling this target.

If not defined, will default to [jvm].default_resolve.

content​

field.type_hint
required

A list of addresses to resources and files targets with content to place in the document root of this WAR file.

dependencies​

field.type_hint
required

Addresses 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 scie-pants-linux-x86_64 dependencies or scie-pants-linux-x86_64 peek on this target to get the final result.

See https://www.pantsbuild.org/v2.18/docs/targets for more about how addresses are formed, including for generated targets. You can also run scie-pants-linux-x86_64 list :: to find all addresses in your project, or scie-pants-linux-x86_64 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.

descriptor​

field.type_hint
required

Path to a file containing the descriptor (i.e., web.xml) for this WAR file. Defaults to web.xml.

shading_rules​

field.type_hint
required

Shading rules to be applied to the individual JAR artifacts embedded in the WEB-INF/lib folder.

There are 4 possible shading rules available, which are as follows:

  • shading_relocate: Relocates the classes under the given package into the new package name. The default target package is __shaded_by_pants__ if none provided in the into parameter.
  • shading_rename: Renames all occurrences of the given pattern by the replacement.
  • shading_zap: Removes from the final artifact the occurrences of the pattern.
  • shading_keep: Keeps in the final artifact the occurrences of the pattern (and removes anything else).

When defining shading rules, just add them in this field using the previously listed rule alias and passing along the required parameters.

output_path​

field.type_hint
required

Where the built asset should be located.

If undefined, this will use the path to the BUILD file, followed by the target name. For example, src/python/project:app would be src.python.project/app.ext.

When running scie-pants-linux-x86_64 package, this path will be prefixed by --distdir (e.g. dist/).

Warning: setting this value risks naming collisions with other package targets you may have.
