 <p>
 These are the instructions for building the Derby jar files
 from the Derby sources.
 </p>

 <h2><a name="Downloads">Downloads</a></h2>

 <p>
 Before building Derby, you need to download the following:

 If you are reading these instructions, chances
   are you have already unpacked a Derby source distribution. However,
   if you don't have the Derby source yet, get the development source tree from subversion by following these
       <a href="http://db.apache.org/derby/dev/derby_source.html">instructions</a>.
       </TD>
     </TR>

     <TR>
       <TD><b><i>Java Development Kit</i></b></TD>
       <TD>You need to install a Java 8 JDK. Probably, your machine

     <TR>
       <TD><b><i>Ant</i></b></TD>

 </TABLE>

 <br/>
 <a name="Downloading JUnit"/>
 <p>
 If you are going to run the Derby tests, then you will need to download the JUnit
 test harness also:

       You can get JUnit 3.8.2 <a href="http://www.junit.org/">here</a>.
       Copy <i>junit.jar</i> into your Derby source tree, in the
       <i>tools/java</i> directory.
       </TD>
     </TR>

   </TBODY>
 </TABLE>

 <br/>
 <br/><br/><br/><hr color="blue"/>
 <h2><a name="Simple Build">Simple Build</a></h2>

 <p>
 Before building Derby, cd
 to the root of your Derby source distribution. That is the top level
 directory which contains the LICENSE and NOTICE files. In addition,
 make sure that the version of Java which you are using is Java 8. You can verify this by checking the output of the following command:
 </p>

 <blockquote>
 <pre><b><font color="blue" size="+2">
 java -version
 </font></b></pre>
 </blockquote>

 <p>
 Now use the following Ant targets to build Derby.:
 </p>

 <TABLE border="2">
   <TBODY>

     <TR>
       <TD><b>Target</b></TD>
       <TD><b>Description</b></TD>

 <blockquote>

       </TD>
     </TR>

     <TR>
       <TD><b><i>buildsource</i></b></TD>
       <TD>This target compiles all source files needed for the Derby
       product. Don't be alarmed by all of the compiler warnings. We'll
       show you how to tidy those up <a href="#Customized Build">later on</a>.
       </TD>
       <TD>
 <blockquote>
 <pre><b><font color="blue" size="+2">

 </blockquote>
       </TD>
     </TR>

     <TR>
       <TD><b><i>buildjars</i></b></TD>
       <TD>This target builds the Derby jar files.</TD>
       <TD>
 <blockquote>

 ant -quiet buildjars
 </font></b></pre>
 </blockquote>
       </TD>
     </TR>

   </TBODY>
 </TABLE>

 <br/>
 <p>
 So, do this:
 </p>

 <blockquote>
 <pre><b><font color="blue" size="+2">
 ant -quiet clobber
 ant -quiet buildsource
 ant -quiet buildjars
 </font></b></pre>
 </blockquote>

 <p>
 In order to build the Derby javadoc, you will need to run another target:
 </p>

 <TABLE border="2">
   <TBODY>

     <TR>
       <TD><b>Target</b></TD>
       <TD><b>Description</b></TD>

     </TR>

   </TBODY>
 </TABLE>

 <blockquote>

 <br/>
 <br/>
 <h3><a name="Verifying the Build">Verifying the Build</a></h3>

 <p>
 Run the <i>sysinfo</i> command to verify that the jars built

 </font></b></pre>
 </blockquote>

 <br/>
 <h3><a name="Testing Derby">Testing Derby</a></h3>

 <p>
 If you want to build and run the Derby tests, make sure that you have downloaded
 the
 <a href="#Downloading JUnit">JUnit</a>
 test framework. Then build all of the Derby sources, including the test classes:
 </p>

 <TABLE border="2">
   <TBODY>

     <TR>
       <TD><b>Target</b></TD>
       <TD><b>Description</b></TD>
       <TD><b>Command</b></TD>
     </TR>

     <TR>
       <TD><b><i>all</i></b></TD>
       <TD>This target compiles all Derby source files.</TD>
       <TD>
 <blockquote>

 ant -quiet all
 </font></b></pre>
 </blockquote>
       </TD>
     </TR>

   </TBODY>
 </TABLE>

 <p>
 Putting all of this together, here's how you build the tests:
 </p>

 <blockquote>
 <pre><b><font color="blue" size="+2">
 ant -quiet clobber
 ant -quiet all
 ant -quiet buildjars
 </font></b></pre>
 </blockquote>

 <p>
 To run the tests, consult the testing
 <a href="./java/testing/README.htm">README</a>.
 </p>

 </blockquote>

 <br/><br/><br/><hr color="blue"/>
 <h2><a name="Customized Build">Customized Build</a></h2>

 <p>
 You can customize the Derby build by setting variables in a file
 called <i>ant.properties</i>. The Ant tool looks for this file in your
 home directory.
 To find out where Ant thinks your home directory is,
 issue the following command and look for "user.home" in the output:
 </p>

 <blockquote>
 <pre><b><font color="blue" size="+2">
 ant -diagnostics
 </font></b></pre>
 </blockquote>

 <br/>
 <p>
 Alternatively, or additionally, you can place properties in a file called 'local.properties' in the top of the source tree. Properties placed in this file have precedence over those in user.home/ant.properties.
 </p>
 <p>
 Here are some Derby-specific variables which you may want to set in <i>ant.properties</i>:
 </p>

       <TD><b><i>sane</i></b></TD>
       <TD>By default, this variable is set to <i>true</i>. This builds
       extra assertion and debugging logic into Derby classes. If you
       set this variable to false, then the Derby jar files will be
       smaller and Derby will run faster. During typical development,
       you will leave this variable set to <i>true</i>. However, this
       variable is set to <i>false</i> when building official Derby releases.</TD>

       <TD>Setting this property will overwrite the default location for
           <i>junit.jar</i>, used to build the tests.
       The default location is <i>tools/java</i>.
       If you set this property, the build will not automatically download
       <i>junit.jar</i>, and if it's not in the specified location, the build will
       stop.</TD>

 <br/>
 <p>
 The default Derby build does NOT necessarily verify that the compile-time contract is
 satisfied for this platform. To get compile-time checks, you
 need to make sure that the following variable is set correctly. To
 see the value which the Derby build uses for this variable, build
 Derby after setting the
 following debug variable in your <i>ant.properties</i>:
 </p>

 <blockquote>
 <pre><b><font color="blue" size="+2">
 printCompilerProperties=true
 </font></b></pre>
 </blockquote>

 <br/>
 <p>
 Here is the variable which determines whether the Derby build
 enforces compile-time contracts for the supported platform:

       the build fails.</TD>

 The preceding variable is mandatory for the Derby build.
 You can also force the setting of the preceding variable by setting the following optional

	<p>
	If you want to build and run the Derby tests, make sure that you have downloaded
	the
	<a href="#Downloading JUnit">JUnit</a>
	test framework. Then build all of the Derby sources, including the test classes:

	<h2><a name="Customized Build">Customized Build</a></h2>

	<p>
	You can customize the Derby build by setting variables in a file
	called <i>ant.properties</i>. The Ant tool looks for this file in your
	home directory.
	To find out where Ant thinks your home directory is,
	issue the following command and look for "user.home" in the output:
	</p>

	<blockquote>
	<pre><b><font color="blue" size="+2">
	ant -diagnostics
	</font></b></pre>
	</blockquote>

	<br/>
	<p>
	Alternatively, or additionally, you can place properties in a file called 'local.properties' in the top of the source tree. Properties placed in this file have precedence over those in user.home/ant.properties.
	</p>
	<p>
	Here are some Derby-specific variables which you may want to set in <i>ant.properties</i>:

	<TR>
	<TD><b><i>sane</i></b></TD>
	<TD>By default, this variable is set to <i>true</i>. This builds
	extra assertion and debugging logic into Derby classes. If you
	set this variable to false, then the Derby jar files will be
	smaller and Derby will run faster. During typical development,
	you will leave this variable set to <i>true</i>. However, this
	variable is set to <i>false</i> when building official Derby releases.</TD>

	<TD><b><i>junit</i></b></TD>
	<TD>Setting this property will overwrite the default location for
	<i>junit.jar</i>, used to build the tests.
	The default location is <i>tools/java</i>.
	If you set this property, the build will not automatically download
	<i>junit.jar</i>, and if it's not in the specified location, the build will
