jvm

Options for general JVM functionality.

JDK strings will be passed directly to Coursier's --jvm parameter. Run cs java --available to see a list of available JVM versions on your platform.

If the string 'system' is passed, Coursier's --system-jvm option will be used instead, but note that this can lead to inconsistent behavior since the JVM version will be whatever happens to be found first on the system's PATH.

Backend: pants.backend.experimental.java
Config section: [jvm]

Basic options

`resolves`

--jvm-resolves="{'key1': val1, 'key2': val2, ...}"
PANTS_JVM_RESOLVES

default:

{
  "jvm-default": "3rdparty/jvm/default.lock"
}

`default_resolve`

--jvm-default-resolve=<str>
PANTS_JVM_DEFAULT_RESOLVE

default: jvm-default

The default value used for the resolve and compatible_resolves fields.

PANTS_JVM_DEBUG_ARGS

For example, if you want to attach a remote debugger, use something like ['-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005']

Advanced options

`tool_jdk`

--jvm-tool-jdk=<str>
