Gradle 6.5 adds file system watching, improving build times
9 June 2020 | 0
Gradle 6.5, the latest version of the popular JVM-based build management tool, has been introduced with an experimental file system watching capability designed to improve build times.
With the opt-in file system watching enabled, Gradle 6.5 can keep what it has learned about the file system in memory between builds rather than polling the system on each build. This optimisation substantially reduces the disk I/O necessary to determine changes since the previous build. Users can enable file system watching by using the parameter,
--watch-fs on the command line.
File system watching will be enabled by default in a future Gradle release. The feature currently has some limitations including a lack of performance benefits for locations with symlinks and a lack of support for SUBST and network drives on Windows.
To switch to Gradle 6.5, developers can update their wrapper: ./
gradlew wrapper --gradle-version=6.5
Other new capabilities in Gradle 6.5 include:
- Improved version dependency ordering, addressing issues such as an algorithm that can lead to potentially confusing results. The improvement is an opt-in feature.
- A security fix for CVE-2020-13165, which has impacted signed artifacts.
- Documentation improvements, with samples covering use cases such as safely using credentials in a build and developing local changes in two independent projects with a composite build.
- For plug-in authors, Gradle now supports using
org.gradle.api.Providerwhen adding dependencies, which is useful for supplying different dependencies based on user-provided configuration.
- For tool providers, IDEs now can use a new method from
GradleConnectorto asynchronously shut down Gradle daemons so they do not continue to use memory and other resources.
Gradle is perhaps best known as the official build tool for Android mobile applications, but it is a general purpose build tool that be used for projects based on JVM languages such as Java and Kotlin or non-JVM languages such as C++, Python, and Swift.
