Eclipse/Ant Build "Failed Build"
Hi. I'm pretty new to this but eager to learn, so I'm hoping this doesn't come of as a stupid Q. And hopefully someone on here has an answer.
I've been trying to build Sweethome 3D using Eclipse and the Build.xml but have run into some minor issues.
First I get this
----------------------------------------- ..\workspace\SweetHome3D\build.xml:40: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not point to the JDK. It is currently set to "C:\Program Files\Java\jre6" ------------------------------------------------------------- I added tools.jar from jdk 1.6.0_17 to the Ant runtime classpath and sure enough that worked.(probably the wrong way to go about it)
Then this when building src\com\eteks\sweethome3d\applet\SweetHome3DApplet.java using Ant and the Build.xml --------------------------------------------------------------- :231: annotations are not supported in -source 1.3 [javac] (use -source 5 or higher to enable annotations) [javac] @SuppressWarnings("unchecked") [javac] ^ [javac] 1 error ----------------------------------------------------------------

Re: Eclipse/Ant Build "Failed Build"
Forget about JAVA_HOME.
Here's my way to run Ant in Eclipse:
select build.xml file in Sweet Home 3D project
choose Run > External Tools > Run As > Ant Build... menu item
in Edit Configuration dialog, select JRE tab
click on Separate JRE radio button,
click on Installed JREs... button,
in Preferences (Filtered) dialog, click on Add... button
in Add JRE dialog, select Standard VM, click on Next > button,
click on Directory... button, and choose the directory of the JDK (not the JRE), probably C:\Program Files\Java\jdk1.6.0_17 under Windows,
click on Finish, and click on OK in Preferences dialog,
in Edit Configuration dialog, select jdk1.6.0_17 as separate JRE
click on Run.
Note that in Targets tab there are many different Ant targets. Don't forget to create keys.keytool file first for javaWebStart, applet and viewer targets (see README.TXT file).

Hi and thanks for replying. I tried your suggestions but nothing seems to make any diffenrence
\SweetHome3D\src\com\eteks\sweethome3d\applet\SweetHome3DApplet.java:231: annotations are not supported in -source 1.3 [javac] (use -source 5 or higher to enable annotations) [javac] @SuppressWarnings("unchecked") [javac] ^ [javac] 1 error

Re: Eclipse/Ant Build "Failed Build"
Don't be astonished if compilation fails: you must have added @SuppressWarnings("unchecked") annotation in SweetHome3DApplet.java and it's not supported in 1.2 source as reported in error message. Some times warnings are left on purpose...
As written in SweetHome3DApplet javadoc: The bytecode of this class is Java 1.1 compatible to be able to notify users that it requires Java 5 when it's run under an old JVM. and again in build.xml: Compile Sweet Home 3D applets first with javac 1.1 to be able to detect current Java version during applet launch (otherwise Java 1.1 to 1.4 plug-ins refuse to load Applet class)
