Java Options Framework

The Java Options Framework contributes arbitrary Java options to the application at runtime.

Detection Criterion java_opts set in the config/java_opts.yml file or the JAVA_OPTS environment variable set
Tags java-opts
Tags are printed to standard output by the buildpack detect script

Configuration

For general information on configuring the buildpack, refer to Configuration and Extension.

The framework can be configured by creating or modifying the config/java_opts.yml file in the buildpack fork.

Name Description
from_environment Whether to append the value of the JAVA_OPTS environment variable to the collection of Java options
java_opts The Java options to use when running the application. All values are used without modification when invoking the JVM. The options are specified as a single YAML scalar in plain style or enclosed in single or double quotes.

Example

# JAVA_OPTS configuration
---
from_environment: false
java_opts: -Xloggc:$PWD/beacon_gc.log -verbose:gc
