本文主要研究一下如何解析pom文件
maven-model
maven提供了maven-model的类库可以直接解析
代码语言：javascript复制 <dependency>
<groupId>org.apache.maven</groupId>
<artifactId>maven-model</artifactId>
<version>3.9.4</version>
</dependency>
使用
代码语言：javascript复制 MavenXpp3Reader xpp3Reader = new MavenXpp3Reader();
Model model = xpp3Reader.read(new ByteArrayInputStream(data));
Properties properties = model.getProperties();
使用MavenXpp3Reader可以直接读取pom文件，之后就可以得到Model
Model
maven-model-3.9.4-sources.jar!/org/apache/maven/model/Model.java
代码语言：javascript复制public class Model extends ModelBase implements Serializable, Cloneable {
private String modelVersion;
private Parent parent;
private String groupId;
private String artifactId;
private String version;
private String packaging = "jar";
private String name;
private String description;
private String url;
private String childProjectUrlInheritAppendPath;
private String inceptionYear;
private Organization organization;
private List<License> licenses;
private List<Developer> developers;
private List<Contributor> contributors;
private List<MailingList> mailingLists;
private Prerequisites prerequisites;
private Scm scm;
private IssueManagement issueManagement;
private CiManagement ciManagement;
private Build build;
private List<Profile> profiles;
private String modelEncoding = "UTF-8";
private File pomFile;
//......
}
Model继承了ModelBase
ModelBase
maven-model-3.9.4-sources.jar!/org/apache/maven/model/ModelBase.java
代码语言：javascript复制public class ModelBase implements Serializable, Cloneable, InputLocationTracker {
private List<String> modules;
private DistributionManagement distributionManagement;
private Properties properties;
private DependencyManagement dependencyManagement;
private List<Dependency> dependencies;
private List<Repository> repositories;
private List<Repository> pluginRepositories;
private Object reports;
private Reporting reporting;
private Map<Object, InputLocation> locations;
private InputLocation location;
private InputLocation modulesLocation;
private InputLocation distributionManagementLocation;
private InputLocation propertiesLocation;
private InputLocation dependencyManagementLocation;
private InputLocation dependenciesLocation;
private InputLocation repositoriesLocation;
private InputLocation pluginRepositoriesLocation;
private InputLocation reportsLocation;
private InputLocation reportingLocation;
//......
}
ModelBase定义了诸如properties、dependencyManagement、dependencies等
小结
maven提供了maven-model可以直接解析pom，它内置了对pom文件的model，可以用来快速分析依赖等。
