It found that execing ant is the best way to get a 1.4 javac build.
I use the following presetdef:
<presetdef name="fork_ant_java14">
<java fork="yes" classname="org.apache.tools.ant.launch.Launcher"
jvm="${java14_exe}">
<classpath>
<path path="${ant.home}/lib/ant-launcher.jar"/>
</classpath>
<env key="JAVA_HOME" value="${env.JAVA14_HOME}"/>
</java>
</presetdef>
Ant figures out where the java14 exe is set based on an enforced env
variable: JAVA14_HOME.
<ac:if>
<available file="${env.JAVA14_HOME}/bin/java.exe"/>
<ac:then>
<property name="java14_exe" location="${env.JAVA14_HOME}/bin/java.exe"/>
<property name="javac14_exe"
location="${env.JAVA14_HOME}/bin/javac.exe"/>
</ac:then>
<ac:else>
<property name="java14_exe" location="${env.JAVA14_HOME}/bin/java"/>
<property name="javac14_exe" location="${env.JAVA14_HOME}/bin/javac"/>
</ac:else>
</ac:if>
And the preset is used as follows:
<fork_ant_java14>
<arg value="-find"/>
<arg value="build.xml"/>
<arg value="comp_grapplet_fork"/>
</fork_ant_java14>
