Build Failure Conditions
In TeamCity you can adjust the conditions when a build should be marked as failed in the Failure Conditions section of the of the Build Configuration Settings page.
To fail a build if sufficient disk space cannot be freed for the build, see the Free disk space build feature.
Common build failure conditions
In the Common Failure Conditions, specify how TeamCity will fail builds by selecting appropriate options from in the Fail build if area:
- it runs longer than ... minutes: Enter a value in minutes to enable execution timeout for a build. If the specified amount of time is exceeded, the build is automatically canceled.
Unless set to 0, this build configuration setting overrides the server-wide default execution timeout specified in Administration -> Global settings.
The default value of 0 means that no limit is set by the build configuration. If there is a server-wide default execution timeout, this default will be used.
This option helps to deal with builds that hang and maintains agent efficiency.
the build process exit code is not zero: Check this option to mark the build as failed if the build process doesn't exit successfully.
at least one test failed: Check this option to mark the build as failed if the build fails at least one test. If this option is not checked, the build can be marked successful even if it fails to pass a number of tests. Regardless of this option, TeamCity will run all build steps.
an error message is logged by build runner: Check this option to mark the build as failed if the build runner reports an error while building.
an out of memory or crash is detected (Java only): Check this option to mark the build as failed if a crash of the JVM is detected, or Java out of memory problems. If possible, TeamCity will upload crash logs and memory dumps as artifacts for such builds.
Additional Failure Conditions
You can instruct TeamCity to mark a build as failed if some of its metrics has deteriorated in comparison with another build, for example, code coverage, artifacts size, and so on. For instance, you can mark build as failed if the code duplicates number is higher than in the previous build.
Another build failure condition causes TeamCity to mark build as failed when a certain text is present in the build log.
To add such build failure condition to your build configuration, click Add build failure condition and select from the list:
Fail build on metric change
When using code examining tools in your build, like code coverage, duplicates finders, inspections and so on, your build generates various numeric metrics. For these metrics you can specify a threshold which, when exceeded, will fail a build.
In general there are two ways to configure this build fail condition:
A build metric exceeds or is less than the specified constant value (threshold).
For example, Fail build if
build duration (secs)compared to constant value is
300. In this case a build will fail if it runs more than 300 seconds.
A build metric has changed comparing to a specific build by a specified value.
For example, Fail build if its
build duration (secs)compared to a value from another build is
moreby at least
300default units for this metric than the value in the
Last successful build. In this case a build will fail if it runs 300 seconds longer than the last successful build. If a branch specification is configured, then the following logic is applied.
Values from the following builds can be used as the basis for comparing build metics:
last successful build
last pinned build
last finished build
build with specified build number
last finished build with specified tag.
By default, TeamCity provides the wide range of build metrics:
artifacts size(bytes) - size of artifacts excluding internal artifacts under
build duration (secs)
number of classes
number of code duplicated
number of covered classes
number of covered lines
number of covered methods
number of failed tests
number of ignored tests
number of inspection errors
number of inspection warnings
number of lines of code
number of methods
number of passed tests
number of tests
percentage of block coverage
percentage of class coverage
percentage of line coverage
percentage of method coverage
percentage of statement coverage
test duration (secs)
total artifacts size (bytes) - size of all artifacts including internal ones
Note that since TeamCity 9.0, the way TeamCity counts tests has changed.
Adding custom build metric
You can add your own build metric. To do so, you need to modify the TeamCity configuration file
<TeamCity Data Directory>/config/main-config.xml and add the following section under "server" node there:
So, if your build publishes the
myMetric value, you can use it as a criterion for a build failure.
Fail build on specific text in build log
TeamCity can inspect all lines in build log for some particular text occurrence that indicates a build failure. Lines are matched without the time and block name prefixes which precede each message in the build log representation.
To configure this build failure condition, specify:
a string or a Java Regular Expression whose presence/absence in the build log is an indicator of a build failure,
a failure message to be displayed on the build results page when a build fails due to this condition.
Stopping build immediately
You can stop a build immediately on encountering a specified text in the build log or when a certain build metric, specified using the Fail build on metric change condition, is exceeded.
