本文以eclipse 4.20为参考.

MANIFEST.MF中常用到的headers,

Manifest-Version: 1.0

无关osgi.

Bundle-ManifestVersion: 2

2对应的是osgi spec relase 4及之后.

Bundle-Name: Firewall

描述性.

Bundle-SymbolicName: org.eclipse.ui.examples.contributions; singleton:=true

bundle的符号名字, 配合版本号可以唯一标识一个bundle. 是manifest.mf的必设项.
singleton默认是false.

Bundle-Version: 3.5.0.qualifier

bundle的版本号. 最多是4段, major.minor.micro.qualifier. 而qualifer允许alphNum, '_‘和’-'字符.
默认值是0.0.0

Bundle-Activator: com.example.Activator

指定activator.

Require-Bundle: org.eclipse.ui;bundle-version="[3.3.0,4.0.0)", org.eclipse.core.runtime

bundle依赖的bundles.

import-Package: org.osgi.util.tracker,org.osgi.service.log;version=1.4

bundle依赖的pakcage.

Export-Package: org.osgi.util.tracker;version=1.3

bundle输出的packages. 逗号间隔.

Require-Capability: osgi.ee; filter:="(&(osgi.ee=AcmeMin)(version=1.1))"

bundle依赖的能力集

Provide-Capability: com.acme.dict; from=nl; to=de; version:Version=1.2

bundle提供的能力集.

Bundle-Localization: plugin

指定bundle使用的localization file. 允许plugin.xml和manifest.mf中使用%XXX引用相应字串.
eclipse中通常指定plugin, 会使用./plugin.properties, plugin_de.properties等
默认指定是 Bundle-Localization: OSGI-INF/l10n/bundle, 即使用./OSGI-INF/l10n/bundle[_local].properties

Bundle-RequiredExecutionEnvironment: JavaSE-11

逗号间隔. bundle的运行环境要求.

Bundle-ActivationPolicy: lazy

lazy指明bundle启动后停留在starting状态, 仅在收到第一次请求后方才进入activated状态. 若不指定Bundle-ActivationPolicy, 则直接进入activated状态, 称作eager activation.

Automatic-Module-Name: com.examples.hello

无关osgi, 这是一个关于java 9开始的modular的header, 用于兼容没有modular descriptor(module-info.java)的传统代码.

Bundle-Category: osgi, test, nursery

指定一组category的名字

Bundle-ClassPath: /jar/http.jar,.

指定jar或bundle内的路径做为class path. ‘.‘是bundle根路径.
默认路径既是’.’

Fragment-Host: org.eclipse.swt; bundle-version="[3.0.0,4.0.0)"

指定该fragment的host bundle.

Bundle-UpdateLocation: http://www.acme.com/Firewall/bundle.jar 一组描述性headers
