Deploytool fails to open in Matlab R2013a.

Hi everyone,

Greetings for the new year!

I have Matlab R2013a and Matlab Compiler 4.18.1. When I click on Matlab Compiler or I type deploytool in command window, I get the following error:

Undefined variable "com" or class
"com.mathworks.mde.deploytool.plugin.PluginManager.allowMatlabThreadUse".

Error in deploytool (line 39)
    com.mathworks.mde.deploytool.plugin.PluginManager.allowMatlabThreadUse()

On line 39, the comment says it calls Java to parse command line.

When I type

version -java

I get answer as

Java 1.6.0_17-b04 with Sun Microsystems Inc. Java HotSpot(TM) 64-Bit Server VM mixed mode

I have downloaded JDK1.6.0_17 version of Java.

Since I am not well versed with Java, I do not know that is causing this problem. The rest of the tool boxes open without any error.

Please help!

Best Regards, Rishi

The error indicates that the MATLAB installation is missing the following java files:

MATLABROOT\java\jar\project\impl.jar

MATLABROOT\java\jar\project\api.jar

In addition, the above two paths should be present in the output of the JAVACLASSPATH, among the static Java paths; if not, the following entries need to be added to "classpath.txt" in "<MATLABROOT>\toolbox\local"

#Java classpath entries for matlab_java_project_api

$matlabroot/java/jar/project/api.jar

#Java classpath entries for matlab_java_project_impl

$matlabroot/java/jar/project/impl.jar

I would suggest reinstalling MATLAB. This should fix all of the above.
