155
156<p>
157 Building Tomcat involves downloading a number of libraries that it depends on.
158 It is strongly recommended to configure download area for those libraries.
159</p>
160
161<p>
162 By default the build is configured to download the dependencies into the
163 <code>${user.home}/tomcat-build-libs</code> directory. You can change this
164 (see below) but it must be an absolute path.
165</p>
166
167<p>
168 The build is controlled by creating a
169 <code>${tomcat.source}/build.properties</code> file. It can be used to
170 redefine any property that is present in <code>build.properties.default</code>
171 and <code>build.xml</code> files. The <code>build.properties</code> file
172 does not exist by default. You have to create it.
173</p>
174
175<p>
176 The download area is defined by property <code>base.path</code>. For example:
177</p>
178
179<div class="codeBox"><pre><code># ----- Default Base Path for Dependent Packages -----
180# Replace this path with the directory path where
181# dependencies binaries should be downloaded.
182base.path=/home/me/some-place-to-download-to</code></pre></div>
183
184<p>
185 Different versions of Tomcat are allowed to share the same download area.
186</p>
187
188<p>
189 Another example:
190</p>
191
192<div class="codeBox"><pre><code>base.path=${user.dir}/../libraries-tomcat7.0</code></pre></div>
193
194<p>
195 Users who access the Internet through a proxy must use the properties
196 file to indicate to Ant the proxy configuration:
197</p>
198
199<div class="codeBox"><pre><code># ----- Proxy setup -----
200proxy.host=proxy.domain
201proxy.port=8080
202proxy.use=on</code></pre></div>

刘洪青6266f992017-05-15 21:21:03 +0800[diff] [blame^]315<code>start-tomcat</code> and <code>stop-tomcat</code> launch configurations are provided in
316<code>res/ide-support/eclipse</code> and will be available in the <em>Run-&gt;Run Configurations</em>
317dialog. Use these to start and stop Tomcat from Eclipse.
318If you want to configure these yourself (or are using a different IDE)
319then use <code>org.apache.catalina.startup.Bootstrap</code> as the main class,
320<code>start</code>/<code>stop</code> etc. as program arguments, and specify <code>-Dcatalina.home=...</code>
321(with the name of your build directory) as VM arguments.
