Types ¶

type Finalizer ¶

type Finalizer struct {
	Stager        common.Stager
	Manifest      common.Manifest
	Installer     common.Installer
	Log           *libbuildpack.Logger
	Command       common.Command
	Container     containers.Container
	JRE           jres.JRE
	ContainerName string
	JREName       string
	BuildpackDir  string
}

func NewFinalizer ¶

func NewFinalizer(stager common.Stager, manifest common.Manifest,
	installer common.Installer, logger *libbuildpack.Logger,
	command common.Command) (*Finalizer, error)

NewFinalizer creates a Finalizer by reading the config.yml written by the supply phase. This follows the pattern established by go-buildpack and dotnet-core-buildpack.

func (*Finalizer) InstallJavaexecLauncher ¶

func (f *Finalizer) InstallJavaexecLauncher() error

InstallJavaexecLauncher copies the javaexec launcher binary into the dependency directory so it is present in the droplet at runtime. The start command (see containers.JavaExecCommand) invokes it as $DEPS_DIR/<idx>/bin/javaexec to tokenize JAVA_OPTS without a shell.

Source path resolution (first match wins):

JAVAEXEC_BINARY_PATH env var — set by bin/finalize for source/git usage where javaexec is built into a temp dir alongside the finalize binary.
<buildpackDir>/bin/javaexec — present in packaged buildpacks built by scripts/build.sh.

The binary is required: missing it means the generated start command would fail at launch, so this returns an error rather than continuing.

type SupplyConfig ¶

type SupplyConfig struct {
	Container  string `yaml:"container"`
	JRE        string `yaml:"jre"`
	JREVersion string `yaml:"jre_version"`
	JavaHome   string `yaml:"java_home"`
}

SupplyConfig holds the values written to config.yml by the supply phase.
