Hello,
when using Ant with a JRE (instead of the JDK), the following message appears:
Unable to locate tools.jar. Expected to find it in C:\Program
Files\Java\jre7\lib\tools.jar
It comes from getToolsJar() in
"ant/src/main/org/apache/tools/ant/launch/Locator.java", which is called
independently of the real need for the classes provided by tools.jar. They seem
to be used only when building a Java application (see details below). However,
Ant is also used for non Java builds, for instance DITA uses Ant, and seems to
work just fine with a JRE. The only inconvenience is the message that appears
in the logs.
It would be great to get rid of the message in this case. What do you think ?
Shall I open a bug report ?
Here are the references to the classes contained in tools.jar, for the record:
ant/build.xml: <available classname="com.sun.tools.javah.Main"/>
ant/build.xml: <available classname="sun.tools.native2ascii.Main"/>
