以编程方式使用IVY依赖关系管理器 [英] using IVY dependencies manager programmatically
问题描述
我需要帮助使用IVY作为依赖关系管理器
我的应用程序需要在RUN-TIME加载插件
意味着在核心应用程序运行时，用户可以请求一个新插件
并安装它们，
i希望使用核心应用程序数据库管理所有已安装的插件。我想从我的插件服务器（或其他描述符）获取一个pom，
并请求IVY告诉我什么是依赖关系，或者让IVY
根据我的应用程序的当前状态安装插件和依赖项
。
（我现在有什么，
1.jar由核心应用程序使用
2.jar由当前安装的插件使用）
我希望每个插件在我的应用程序所在的某个文件夹（不是共享文件夹）下具有独立目录
我不知道从哪里开始
i注意到没有编程API
我找到一个人的网络上的一个链接，尝试类似的
但看起来像代码没有完成，或一些变量缺少
，我不知道如何完成休息的编程文档湖

（其中变量艺术来自.....）
你可以帮我吗...
谢谢所有的

i我得到一些错误加上我不知道如何定义我的archiva服务器
IvySettings settings = new IvySettings（） ;
settings.setDefaultIvyUserDir（new File（D：/ programming / eclipse_projects / ivyTest / repo /））;
settings.setDefaultCache（new File（D：/ programming / eclipse_projects / ivyTest / repo / cache /））;
settings.setDefaultCacheArtifactPattern（[module] / [revision] / [module] - [revision]（ - [classifier]）;
Ivy ivy = Ivy.newInstance（settings）
ivy.getLoggerEngine（）。pushLogger（new DefaultMessageLogger（Message.MSG_VERBOSE））;
ModuleDescriptor md = PomModuleDescriptorParser.getInstance（）。parseDescriptor（new IvySettings（），new文件（src / movies.pom）toURL（），true）;
RetrieveOptions retriveOptions = new RetrieveOptions（）;
retriveOptions.setUseOrigin（true）;
retriveOptions .setConfs（md.getConfigurationsNames（））;
ivy.retrieve（md.getModuleRevisionId（），lib / [conf] / [artifact]。[ext]，etriveOptions）;
这是我得到的错误

常春藤可以用作独立的Java程序：
java -jar ivy.jar -retrievelib / [conf] / [artifact]。[ext]
检索用于确定文件的安装位置，基于ivy配置设置
$ find lib -type f
lib / core / commons-lang.jar
lib / plugin1 / commons-logging.jar
lib / plugin1 / commons-codec.jar
lib / plugin2 / commons-logging.jar
lib / plugin2 / commons-cli.jar
lib / plugin3 / commons-logging.jar
配置用作集合标签或依赖关系的分组。它们类似于Maven范围，但更灵活：
< ivy-module version =2.0>
< info organization =com.myspotonthewebmodule =demo/>
<配置>
< conf name =coredescription =核心应用程序依赖关系/>
< conf name =plugin1description =Plugin 1 dependencies/>
< conf name =plugin2description =Plugin 2 dependencies/>
< conf name =plugin3description =Plugin 3 dependencies/>
< / configurations>
<依赖关系>
< dependency org =commons-langname =commons-langrev =2.5conf =core-> default/>
< dependency org =commons-codecname =commons-codecrev =1.4conf =plugin1-> default/>
< dependency org =commons-cliname =commons-clirev =1.2conf =plugin2-> default/>
< dependency org =commons-loggingname =commons-loggingrev =1.1.1conf =plugin1，plugin2，plugin3-> default/>
< / dependencies>
< / ivy-module>
如果您只想下载并安装一组jar，可以在指定的目录中使用 confs 参数：
java -jar ivy.jar -retrieveplugin1 / [artifact] ext]-confs plugin1
最后，如果您仍然想使用编程API，可以调用主要调用的运行方法

更新1
Groovy已经建立了对调用ivy任务的支持
import groovy.xml.NamespaceBuilder
def ant = new AntBuilder（）
def ivy = NamespaceBuilder.newInstance（ant，'antlib：org.apache.ivy.ant'）
ivy.settings（file：ivysettings.xml ）
ivy .retrieve（pattern：lib / [conf] / [artifact]。[ext]）
ivy.report（toDir：'reports'，graph：false）
更新2
要设置本地Maven存储库的位置，您需要使用 ivysettings.xml 文件。
< ivysettings>
< settings defaultResolver ='nexus'/>
< resolvers>
< ibiblio name ='nexus'root ='http：//myhost.mydomanin.com：8081 / nexus'm2compatible ='true'/>
< / resolvers>
< / ivysettings>

详细说明如何从Java调用Ivy
i need help using IVY as dependencies manager
my application need to load plug-ins at RUN-TIME
means while the core application is running ,user can request for a new plug-in
and install them ,
i wish to manage all installed plug-ins using the core application DB.
i want to get a pom from my plug-ins server (or some other descriptor),
and ask IVY to tell me what are the dependencies OR let IVY
install the plug-in and dependencies ,
based on the current state of my application.
( what do i have right now ,
1.jar's used by core application
2.jar's used by current installed plug-ins)
i wish for each plug-in to have independent directory
under some folder where my application is located (not a shared one)
the thing is i don't know where to start
i notice that there is no programming API for that
i located one link over the network of someone who try something similar
but look likes the code is not completed , or some variable are missing
and i dont know how to complete the rest cause lake of programming documentation
http://www.mail-archive.com/ivy-user@ant.apache.org/msg03228.html
(where the variable "art" came for.....)
can you help me please ... Thank you all
UPDATE
ok this what i am trying now . i am getting some a error plus i dont know how to define my archiva server
IvySettings settings = new IvySettings();
settings.setDefaultIvyUserDir(new File("D:/programming/eclipse_projects/ivyTest/repo/"));
settings.setDefaultCache(new File("D:/programming/eclipse_projects/ivyTest/repo/cache/"));
settings.setDefaultCacheArtifactPattern("[module]/[revision]/[module]-[revision](-[classifier]");
Ivy ivy = Ivy.newInstance(settings);
ivy.getLoggerEngine().pushLogger(new DefaultMessageLogger(Message.MSG_VERBOSE));
ModuleDescriptor md = PomModuleDescriptorParser.getInstance().parseDescriptor(new IvySettings(), new File("src/movies.pom").toURL(), true);
RetrieveOptions retriveOptions = new RetrieveOptions();
retriveOptions.setUseOrigin(true);
retriveOptions.setConfs(md.getConfigurationsNames());
ivy.retrieve(md.getModuleRevisionId(), "lib/[conf]/[artifact].[ext]", etriveOptions);
this is the error i get

Ivy can be used as a standalone java program:
java -jar ivy.jar -retrieve "lib/[conf]/[artifact].[ext]"
The retrieve pattern can be then used to determine where files are installed, based on the ivy configuration settings
$ find lib -type f
lib/core/commons-lang.jar
lib/plugin1/commons-logging.jar
lib/plugin1/commons-codec.jar
lib/plugin2/commons-logging.jar
lib/plugin2/commons-cli.jar
lib/plugin3/commons-logging.jar
Configurations are used as a collective label or grouping of dependencies. They are similar to Maven scopes but much more flexible:
<ivy-module version="2.0">
<info organisation="com.myspotontheweb" module="demo"/>
<configurations>
<conf name="core" description="Core application dependencies"/>
<conf name="plugin1" description="Plugin 1 dependencies"/>
<conf name="plugin2" description="Plugin 2 dependencies"/>
<conf name="plugin3" description="Plugin 3 dependencies"/>
</configurations>
<dependencies>
<dependency org="commons-lang" name="commons-lang" rev="2.5" conf="core->default"/>
<dependency org="commons-codec" name="commons-codec" rev="1.4" conf="plugin1->default"/>
<dependency org="commons-cli" name="commons-cli" rev="1.2" conf="plugin2->default"/>
<dependency org="commons-logging" name="commons-logging" rev="1.1.1" conf="plugin1,plugin2,plugin3->default"/>
</dependencies>
</ivy-module>
If you only want to download and install one set of jars, into a specified directory you can use the confs parameter:
java -jar ivy.jar -retrieve "plugin1/[artifact].[ext]" -confs plugin1
Finally, if you still want to use a programming API, you could invoke the run method called by the main class
http://svn.apache.org/viewvc/ant/ivy/core/trunk/src/java/org/apache/ivy/Main.java?view=markup
Update 1
Groovy has built in support for invoking ivy tasks
import groovy.xml.NamespaceBuilder
def ant = new AntBuilder()
def ivy = NamespaceBuilder.newInstance(ant, 'antlib:org.apache.ivy.ant')
ivy.settings(file:"ivysettings.xml")
ivy.retrieve(pattern:"lib/[conf]/[artifact].[ext]")
ivy.report(toDir:'reports', graph:false)
Update 2
To set the location of your local Maven repository you need to use an ivysettings.xml file.
<ivysettings>
<settings defaultResolver='nexus' />
<resolvers>
<ibiblio name='nexus' root='http://myhost.mydomanin.com:8081/nexus' m2compatible='true' />
</resolvers>
</ivysettings>
Update 3
Just found an article that details how to invoke Ivy from Java
