因为每次构建不一定会升级版本号，为了把artifact和版本对应起来，可以使用git-commit-id-plugin插件。
引入插件
<plugin>
<groupId>pl.project13.maven</groupId>
<artifactId>git-commit-id-plugin</artifactId>
<version>4.0.0</version>
<executions>
<execution>
<id>get-the-git-infos</id>
<goals>
<goal>revision</goal>
</goals>
<phase>initialize</phase>
</execution>
</executions>
<configuration>
<generateGitPropertiesFile>true</generateGitPropertiesFile>
<generateGitPropertiesFilename>${project.build.outputDirectory}/git.properties</generateGitPropertiesFilename>
<includeOnlyProperties>
<includeOnlyProperty>^git.build.(time|version)$</includeOnlyProperty>
<includeOnlyProperty>^git.commit.id.(abbrev|full)$</includeOnlyProperty>
</includeOnlyProperties>
<commitIdGenerationMode>full</commitIdGenerationMode>
</configuration>
</plugin>
git-commit-id-plugin能够收集比较多的git信息，因此使用includeOnlyProperties指定需要保留的信息。
所有支持的属性参见：GitCommitPropertyConstant.java:
public class GitCommitPropertyConstant {
// these properties will be exposed to maven
public static final String BRANCH = "branch";
public static final String LOCAL_BRANCH_AHEAD = "local.branch.ahead";
public static final String LOCAL_BRANCH_BEHIND = "local.branch.behind";
public static final String DIRTY = "dirty";
// only one of the following two will be exposed, depending on the commitIdGenerationMode
public static final String COMMIT_ID_FLAT = "commit.id";
public static final String COMMIT_ID_FULL = "commit.id.full";
public static final String COMMIT_ID_ABBREV = "commit.id.abbrev";
public static final String COMMIT_DESCRIBE = "commit.id.describe";
public static final String COMMIT_SHORT_DESCRIBE = "commit.id.describe-short";
public static final String BUILD_AUTHOR_NAME = "build.user.name";
public static final String BUILD_AUTHOR_EMAIL = "build.user.email";
public static final String BUILD_TIME = "build.time";
public static final String BUILD_VERSION = "build.version";
public static final String BUILD_HOST = "build.host";
public static final String BUILD_NUMBER = "build.number";
public static final String BUILD_NUMBER_UNIQUE = "build.number.unique";
public static final String COMMIT_AUTHOR_NAME = "commit.user.name";
public static final String COMMIT_AUTHOR_EMAIL = "commit.user.email";
public static final String COMMIT_MESSAGE_FULL = "commit.message.full";
public static final String COMMIT_MESSAGE_SHORT = "commit.message.short";
public static final String COMMIT_TIME = "commit.time";
public static final String REMOTE_ORIGIN_URL = "remote.origin.url";
public static final String TAGS = "tags";
public static final String CLOSEST_TAG_NAME = "closest.tag.name";
public static final String CLOSEST_TAG_COMMIT_COUNT = "closest.tag.commit.count";
public static final String TOTAL_COMMIT_COUNT = "total.commit.count";
}
这些变量可以在pom中使用，比如增加到artifact的文件名中：
<properties>
<version.number>${git.commit.time}.${git.commit.id.abbrev}</version.number>
</properties>
完整使用手册参见：using-the-plugin
默认会在target/classess目录增加git.properties文件。
