29Unpack the binary distribution into a convenient location so that the

37Create an ANT_HOME environment variable to point the directory ${ant.home},
38and modify the PATH environment variable to include directory
39"${ant.home}/bin" in its list.  This makes the "ant" command line script
40available, which will be used to actually perform the build.

80WARNING: Running this command will download binaries to the
81  <code>/usr/share/java</code> directory.
82  Make sure this is appropriate to do so on your computer. On Windows,
83  this usually corresponds to the <code>C:\usr\share\java</code> directory,
84  unless Cygwin is used. Read below to customize the directory used
85  to download the binaries.

89The build can be controlled by creating a ${tomcat.source}/build.properties
90  file, and adding the following content to it:
91<code><br>
92    # ----- Proxy setup -----<br>
93    # Uncomment if using a proxy server.<br>

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

178The same caveats apply as for Eclipse, above.

182The same general idea should work in most IDEs; it has been reported
183to work in Idea, for example.
