Question

我对WSO2 ESB有另一个问题。我已经创建了一些Maven项目。该项目包含在WSO2的Java库项目中。在库项目中，我在pom.xml中设置了maven-bundle-plugin。它通过Maven构建正确地创建了MANIFEST，但是将项目导出为可部署档案库创建的MANIFEST.md具有旧属性（我认为，通过Eclipse创建新项目后，MANIFEST具有属性（未更改SymbolicName，无导入）。

Maven项目带有捆绑POM.xml的类

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.coig.esb.osgi</groupId>
  <artifactId>emf</artifactId>
  <version>1.0.0</version>
  <packaging>jar</packaging>

  <name>emf</name>
  <url>http://maven.apache.org</url>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>

    <!-- https://mvnrepository.com/artifact/javax.persistence/javax.persistence-api -->
  <dependency>
      <groupId>javax.persistence</groupId>
      <artifactId>javax.persistence-api</artifactId>
      <version>2.2</version>
  </dependency>

  </dependencies>
</project>

然后将上述项目中的jar文件从WSO2导入Java库项目中。

当我创建Mediator项目时，将maven-bunlde-plugin设置为导入我之前提到的模块，情况相同。 Maven构建会创建正确的MANIFEST.md，但是将项目导出为可部署存档会创建具有不变属性的MANIFEST.md。

您能给我一些备注吗，应该如何设置？

Answer 1

类似“将项目导出为可部署的存档”之类的文件不支持MANIFEST.MF中的Import-Package标头。该文件由MediatorExportHandler类构建，该类忽略此标头。

IJavaProject javaProject = JavaCore.create(project);

List<String> exportPac =getExportPackages(javaProject);
BundleManifest manifest = new BundleManifest();    
manifest.setBundleName(project.getName());
manifest.setBundleSymbolicName(project.getName());
manifest.setBundleDescription(project.getName());
manifest.setBundleVersion("2.0");
manifest.setExportPackagesList(exportPac);
[...]
File manifestFile=new File(metainfPath,"MANIFEST.MF");
FileUtils.createFile(manifestFile, manifest.toString());

WSO2和创建可部署的存档会使用Maven中的旧属性
