在Eclipse中运行Nutch - 缺少构建文件夹

Question

Hi I was following this tutorial trying to run Nutch in Eclipse and run Nutch step by step.

I finished this step (Nutch 1.X) without problem:

 svn co https://svn.apache.org/repos/asf/nutch/trunk
 cd trunk

Since I was working on 1.X , so I skipped to step#5. However, it mentioned:

Add “http.agent.name” and “http.robots.agents” with appropiate values in “conf/nutch-site.xml”. See conf/nutch-default.xml for the description of these properties. Also, add “plugin.folders” and set it to {PATH_TO_NUTCH_CHECKOUT}/build/plugins. eg. If Nutch is present at "/home/tejas/Desktop/2.x", set the property to:

 <property>
   <name>plugin.folders</name>
   <value>/home/tejas/Desktop/2.x/build/plugins</value>
 </property>

So here is my question:

(1). There is no nutch-site.xml file in the trunk/conf folder as default, however, there is a nutch-site.xml.template file which I renamed to nutch-site.xml to use.

(2). {PATH_TO_NUTCH_CHECKOUT}/build/plugins , I really don't know where this build folder is located. This is what I have done:

trunk$ find . | grep build
./.svn/prop-base/build.xml.svn-base
./.svn/text-base/build.xml.svn-base
./build.xml
./src/plugin/.svn/prop-base/build-plugin.xml.svn-base
./src/plugin/.svn/prop-base/build.xml.svn-base
...

Clearly there is no folder called 'build', neither 'plugins'.

Then should I just take the ./src/plugin as the ./build/plugins folder and move on? I don't have that much experience building from source so any advise is appreciated!

Here is the answer to your question:

1) Yes. You are correct you have to rename the nutch-site.xml.template file to nutch-site.xml and make the changes accordingly.

2) There is no /build/plugins folder currently present. But when you run the "ant eclipse" command you will get the "/build/plugins" in your {PATH_TO_NUTCH_CHECKOUT} Thats why it is written as set the absolute path as {PATH_TO_NUTCH_CHECKOUT}/build/plugins Do not give relative path here as it wont.

Hope this helps you!!!
