Relentless

The <relentless> task will execute all of the nested tasks, regardless of whether one or more of the nested tasks fails. When <relentless> has completed executing the nested tasks, it will either

fail, if any one or more of the nested tasks failed; or
succeed, if all of the nested tasks succeeded.

An appropriate message will be written to the log.

Tasks are executed in the order that they appear within the <relentless> task. It is up to the user to ensure that relentless execution of the nested tasks is safe.

This task only works for ant version greater than or equal to ant 1.6.0.

Parameters

Attribute	Description	Required
description	A string that will be included in the log output. This can be useful for helping to identify sections of large Ant builds.	No
terse	Setting this to `true` will eliminate some of the progress output generated by <relentless>. This can reduce clutter in some cases. The default value is `false`.	No

Nested elements

task list

The only nested element supported by <relentless> is a list of tasks to be executed. At least one task must be specified.

It is important to note that <relentless> only proceeds relentlessly from one task to the next - it does not apply recursively to any tasks that might be invoked by these nested tasks. If a nested task invokes some other list of tasks (perhaps by <antcall> for example), and one of those other tasks fails, then the nested task will stop at that point.

Example

A relentless task to print out the first five canonical variable names:

<relentless description="The first five canonical variable names.">
    <echo>foo</echo>
    <echo>bar</echo>
    <echo>baz</echo>
    <echo>bat</echo>
    <echo>blah</echo>
</relentless>

which should produce output looking more or less like

[relentless] Relentlessly executing: The first five canonical variable names.
[relentless] Executing: task 1
     [echo] foo
[relentless] Executing: task 2
     [echo] bar
[relentless] Executing: task 3
     [echo] baz
[relentless] Executing: task 4
     [echo] bat
[relentless] Executing: task 5
     [echo] blah
[relentless] All tasks completed successfully.

If you change the first line to set the terse parameter,

    <relentless terse="true" description="The first five canonical variable names."/>

the output will look more like this:

[relentless] Relentlessly executing: The first five canonical variable names.
     [echo] foo
     [echo] bar
     [echo] baz
     [echo] bat
     [echo] blah
[relentless] All tasks completed successfully.

If we change the third task to deliberately fail

<relentless terse="true" description="The first five canonical variable names.">
    <echo>foo</echo>
    <echo>bar</echo>
    <fail>baz</fail>
    <echo>bat</echo>
    <echo>blah</echo>
</relentless>

then the output should look something like this.

[relentless] Relentlessly executing: The first five canonical variable names.
     [echo] foo
     [echo] bar
[relentless] Task task 3 failed: baz
     [echo] bat
     [echo] blah
