Versioning your module

Module version information

Across modules have version information attached in the form of an AcrossVersionInfo property. This object provides information like the current version and time when it was built. By default this information is fetched automatically from the META-INF/MANIFEST.MF resource. The following attributes are required for a fully configured AcrossVersionInfo instance:

Table 1. MANIFEST attributes
Attribute Example Description

Implementation-Title

across-web

Name of the project the class (AcrossModule) belongs to. Often also the JAR name.

Implementation-Version

{across-version}

Build version of the AcrossModule.

Build-Time

20150831-1011

Timestamp when the version was built (in yyyyMMdd-HHmm format).

Using Maven a valid MANIFEST file can automatically be created using the following plugin configuration:

<plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-jar-plugin</artifactId>
       <version>2.6</version>
       <configuration>
           <archive>
               <manifest>
                   <addDefaultImplementationEntries>true</addDefaultImplementationEntries>
               </manifest>
               <manifestEntries>
                   <Build-Time>${maven.build.timestamp}</Build-Time>
               </manifestEntries>
           </archive>
       </configuration>
   </plugin>
