Field Detail

command

protected final String command

Command to execute. The format depends on the actual CommandInterpreter implementation.

configuredLocalRules

@Restricted(org.kohsuke.accmod.restrictions.Beta.class)
protected List<EnvVarsFilterLocalRule> configuredLocalRules

List of configured environment filter rules

protected CommandInterpreter(String command)

Method Detail

getCommand

public final String getCommand()

buildEnvVarsFilterRules

@NonNull
public List<EnvVarsFilterLocalRule> buildEnvVarsFilterRules()

Description copied from interface: EnvVarsFilterableBuilder

The order is respected for the execution. Local rules will be executed before the global ones. This method is called only once per step to create the EnvVarsFilterRuleContext. The default implementation returns an empty list; this allows build steps to support global rules.

Specified by:

buildEnvVarsFilterRules in interface EnvVarsFilterableBuilder

getConfiguredLocalRules

@Restricted(org.kohsuke.accmod.restrictions.NoExternalUse.class)
public List<EnvVarsFilterLocalRule> getConfiguredLocalRules()

perform

public boolean perform(AbstractBuild<?,?> build,
                       Launcher launcher,
                       BuildListener listener)
                throws InterruptedException

Description copied from interface: BuildStep

Runs the step over the given build and reports the progress to the listener.

A plugin can contribute the action object to Actionable.getActions() so that a 'report' becomes a part of the persisted data of Build. This is how JUnit plugin attaches the test report to a build page, for example.

When this build step needs to make (direct or indirect) permission checks to ACL (for example, to locate other projects by name, build them, or access their artifacts) then it must be run under a specific Authentication. In such a case, the implementation should check whether Jenkins.getAuthentication2() is ACL.SYSTEM2, and if so, replace it for the duration of this step with Jenkins.ANONYMOUS. (Either using ACL.impersonate2(org.springframework.security.core.Authentication), or by making explicit calls to ACL.hasPermission2(Authentication, Permission).) This would typically happen when no QueueItemAuthenticator was available, configured, and active.

Specified by:

perform in interface BuildStep

Overrides:

perform in class BuildStepCompatibilityLayer

Returns:

Delegates to SimpleBuildStep.perform(Run, FilePath, Launcher, TaskListener) if possible, always returning true or throwing an error.

Throws:

InterruptedException - If the build is interrupted by the user (in an attempt to abort the build.) Normally the BuildStep implementations may simply forward the exception it got from its lower-level functions.

isErrorlevelForUnstableBuild

protected boolean isErrorlevelForUnstableBuild(int exitCode)

Determines whether a non-zero exit code from the process should change the build status to Result.UNSTABLE instead of default Result.FAILURE. Changing to Result.UNSTABLE does not abort the build, next steps are continued.

Since:

2.26

perform

public boolean perform(AbstractBuild<?,?> build,
                       Launcher launcher,
                       TaskListener listener)
                throws InterruptedException

Throws:

InterruptedException

join

protected int join(Proc p)
            throws IOException,
                   InterruptedException

Reports the exit code from the process. This allows subtypes to treat the exit code differently (for example by treating non-zero exit code as if it's zero, or to set the status to Result.UNSTABLE). Any non-zero exit code will cause the build step to fail. Use isErrorlevelForUnstableBuild(int exitCode) to redefine the default behaviour.

Throws:

IOException

InterruptedException

Since:

1.549

createScriptFile

public FilePath createScriptFile(@NonNull
                                 FilePath dir)
                          throws IOException,
                                 InterruptedException

Creates a script file in a temporary name in the specified directory.

Throws:

IOException

InterruptedException

buildCommandLine

public abstract String[] buildCommandLine(FilePath script)

getContents

protected abstract String getContents()

getFileExtension

protected abstract String getFileExtension()
