76NOTE: Users accessing the Internet through a proxy must use a properties

81WARNING: Running this command will download binaries to the
82  <code>/usr/share/java</code> directory.
83  Make sure this is appropriate to do so on your computer. On Windows,
84  this usually corresponds to the <code>C:\usr\share\java</code> directory,
85  unless Cygwin is used. Read below to customize the directory used
86  to download the binaries.

90The build can be controlled by creating a ${tomcat.source}/build.properties
91  file, and adding the following content to it:
92<code><br>
93    # ----- Proxy setup -----<br>
94    # Uncomment if using a proxy server.<br>
95    #proxy.host=proxy.domain<br>

109<b>Important:</b>
110This is not a supported means of building Tomcat; this information is
111provided without warranty :-).
112The only supported means of building Tomcat is with the "ant build"
113described above.
114However, some developers like to work on Java code with a Java IDE,
115and the following steps have been used by some developers.
116</p>
117
118<p>
119Note that you <b>must</b> complete all the above steps to fetch
120the repositories and build some JAR files the first time.
121After you have completed the above steps, you can set up a
122series of Eclipse 4 projects.
123<b>Note</b> that this will not let you build everything under Eclipse;
124the build process requires use of Ant for the many stages that aren't
125simple Java compilations.
126However, it will allow you to view and edit the Java code,
127get warnings, reformat code, perform refactorings, run Tomcat
128under the IDE, and so on.
129</p>
130
131<p>
132Use Windows-&gt;Preferences and then Java-&gt;Build Path-&gt;Classpath
133Variables to add two new Classpath variables:
134</p>
135
136<p>
137<table border="1">
138 <tr><td>TOMCAT_LIBS_BASE</td><td>the base path where the binary dependencies have been downloaded</td></tr>
139 <tr><td>ANT_HOME</td><td>the base path of Ant 1.6.2 or later</td></tr>
140</table>
141</p>
142
143<p>
144Use File-&gt;New Project to create a new Java project
145for each of the binaries repository (e.g., /usr/share/java),
146container, connectors, jasper, servletapi.
147Unless you thought ahead to make the ${tomcat.source} directory be under
148your Workspace folder, tell Eclipse the external location using "Import/Export...",
149General-&gt;Existing Project into Workspace.
150</p>
151
152<p>
153Eclipse .project and .classpath files are provided in each of these
154directories so Eclipse should find all source trees and jars, and
155hopefully compile without problems. <b>Note</b> that these
156files assume you are using Eclipse with a 5.0 or later JDK; also, the
157connectors module must be built with a compiler compliance level of 5.0.
158</p>
159
160<p>
161To run Tomcat without a special IDE plug-in, you can simply use Run-&gt;Run...
162enter "org.apache.catalina.startup.Catalina" as the main class,
163"start" as program arguments, and
164"-Dcatalina.home=..." (with the name of your build directory)
165as VM arguments.
166</p>
167
168<p>
169Note also that due to the way the Tomcat source is assembled
170from several SVN projects, you may not be able to use the Eclipse
171SVN client to update (nor to commit, if you are a committer).
172Use the external SVN client of your choice, then use the
173Eclipse PackageExplorer or Navigator "Refresh" context menu item
174to tell Eclipse that you've updated the files.
