1/20/2024 0 Comments Maven current version![]() ![]() ![]() In a continuous integration environment, the SNAPSHOT version plays a vital role in keeping the integration build up-to-date while minimizing the amount of rebuilding that is required for each integration step. If a version number is followed by -SNAPSHOT, then Maven considers it the "as-yet-unreleased" version of the associated MajorVersion, MinorVersion, or IncrementalVersion. Maven treats the SNAPSHOT qualifier differently from all others. See Section 7.3 for information about version changes. Version resolution is also very important if you intend to use version ranges in your dependency references. Given the preceding example sequence, if your current reference was 1.0.10.2, then the plug-in would report 1.0.9.3 as a newer release. If Maven incorrectly identifies a newer release, then it is also reported incorrectly in the plug-in. When you are coordinating a large release, this goal can help you to find stale references in dependency configuration. The versions:dependency-updates-report goal examines a project's dependency hierarchy and reports which ones have newer releases available. One useful goal is versions:dependency-updates-report. The Maven Versions plug-in provides goals to check your project dependencies for currency in a different ways. 3) forced Maven to evaluate the version as a string.Īn example of this effect on Maven is found in the Maven Versions plug-in. Version 1.0.9.3 should come before 1.0.10.1 and 1.0.10.2, but the unexpected fourth field (. Because basic string comparison is performed on nonstandard versions, version comparison calculates the order of versions incorrectly in some cases.įor example, Maven arranges the version list in the following manner: If you use a nonstandard versioning scheme, Maven release and version plug-in goals might not yield the expected results. Maven and its core plug-ins use version comparison for a number of tasks, most importantly, the release process. If you do not follow Maven versioning standards in your project versioning scheme, then for version comparison, Maven interprets the entire version as a simple string. Identical versions with different qualifier fields are compared by using basic string comparison. version=1.0.Maven's versioning scheme uses the following standards:Īll versions with a qualifier are older than the same version without a qualifier (release version). Now, when the build is executed we end up with the version number and build time of the application in the version.txt file. ![]() The is an optional property for (obviously) defining the timestamp format. The workaround is to create another property within the pom.xml file and set that new property to the timestamp value, in this case, the property name is “timestamp”, which is used above in the version.txt file. version=$ property from getting passed to the resource filtering mechanism. I started with a version.txt file at the default package level in src/main/resources of my project, which looks as follows. ![]() Stamping the version number and the build time of an application in a properties file so that it could be displayed by an application at runtime seemed like it should be a pretty straightforward task, although it took a bit of time to find a solution that didn’t require the timestamp, version, or ant-run plugins. ![]()
