The user interface update that we started in the previous version continues in 2018.1. In this EAP build the build line has been redesigned a bit, but this is still a work in progress.
Agent history page now looks similar to "All builds page" (which was introduced in 2017.2.x):
If you want to see other experimental user interface features, click on "Experimental UI" toggle at the top.
In the current TeamCity version, if a build step is defined in a template, it is shown as read-only in a build configuration inheriting this build step. If some customization is required, then a parameter reference has to be defined for some settings in the template, and a specific value should be set for this parameter in the build configuration. However, this workaround works for text fields only.
In this EAP it is finally possible to customize an inherited build step, i.e. it is possible to change every setting of the inherited build step without the need to introduce parameters.
Note that the redefined build step preserves its place in the steps order. Note that overriding any property in an inherited BC will fix all the other values in the resulting build config, and changing other properties of the same feature in a template will not take affect. It concerns build steps, triggers, build features, artifact deps, agent reqs, failure conditions.
There is sometimes a need to define a common build step in a template, so that this step will be executed either before all build configuration steps or after them.
In this EAP build, for a given template it is possible to define such steps and then define their placement in respect to the build configuration steps. All build configuration steps are represented as a placeholder in the Reorder Build Steps dialog. The template steps can be placed before or after this placeholder.
Note: you still can have a completely custom order of steps in a build configuration inherited from a template.
Now when re-running a build, TeamCity preserves all the custom parameters of this build and its dependencies as of the time of the original run.
Besides that, on the dependencies tab, there is now an additional option to rerun the failed/failed to start or cancelled dependencies of the build:
Since this EAP shared resources can be locked not only for regular builds, but for composite builds as well. A lock on the specified resource will be acquired when a composite build starts (when the first build of the composite build chain starts); the lock will be released when the composite build finishes (the last build in its chain is finished).
The locks acquired on composite builds affect only these composite builds and are not propagated to their individual parts.
For example, if a resource has a quota of N, then N composite builds that have a read lock on this resource can be run concurrently. The number of concurrent individual builds inside these composite builds will not be affected by the resource quota.
Adding a lock on a composite build is done the same way it is done for a regular build: it can be done by adding the Shared Resources build feature.
Java 9 and Java 10 can now be used to run an agent
