Gradle goodness:continue Build even with Failed Tasks

If We run a Gradle build and one of the tasks fails, the whole build stops immediately. We have the fast feedback of our build status. If we don ' t want to this and want Gradle to execute all tasks, even though some might has failed, we use the command line Option --continue . When we use the --continue command line option Gradle would execute every task where the dependent tasks is not failing. This was also useful in a multi-module project where we might want to build all projects even though some could have failing Tests, so we get a complete overview of failed tests for all modules.

In the following Gradle build file, we have both tasks. The task failTask throws a to TaskExecutionException purposely fail the task. The would not successTask fail:

View Sourceprint? 00. task failTask << { task -> 01. println "Running ${task.name}" 02.  03. throw new TaskExecutionException( 04. task, 05. new Exception( ‘Fail task on purpose‘ )) 06. } 07.  08. task successTask << { 09. println "Running ${it.name}" 10. }

Let's run both tasks from the command line and see the output:

$ gradle failTask successTask :failTask Running failTask :failTask FAILED  FAILURE: Build failed with an exception.  * Where: Build file ‘/Users/mrhaki/samples/gradle/continue/build.gradle‘ line: 4  * What went wrong: Execution failed for task ‘:failTask‘. > Fail task on purpose  * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.  BUILD FAILED  Total time: 4.148 secs $

We See the build have failed and only the task is failTask executed. Now we run the same to the tasks, but we use the command line option --continue :

$ gradle --continue failTask successTask :failTask Running failTask :failTask FAILED :successTask Running successTask  FAILURE: Build failed with an exception.  * Where: Build file ‘/Users/mrhaki/samples/gradle/continue/build.gradle‘ line: 4  * What went wrong: Execution failed for task ‘:failTask‘. > Fail task on purpose  * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.  BUILD FAILED  Total time: 6.918 secs $

This was successTask executed even though the has failTask failed again. Gradle would keep track of all tasks, which has failed and displays a summary with all the tasks, that has failed.
