Sencha CMD build classic app not working but modern does

Question

I have sencha Universal app. Recently i switched from windows to Linux so i have to reinstall everything. Now my sencha CMD version is v6.7.0.63 , app version is 6.2.167. When i try to create new app with CMD it is successfully creating the new app, and sencha app build classic on this newly created app is also good. But when i try to build the old app, it is not working. My Old app build ios is also working. But not the classic.

Here is the error it gives when i run sencha app build classic

Exception information:

Sencha/Cmd/6.7.0.63/plugin.xml:333: The following error occurred while executing this line: htdocs/pi-v3/public/App/.sencha/app/build-impl.xml:273: The following error occurred while executing this line: htdocs/pi-v3/public/App/.sencha/app/js-impl.xml:186: com.sencha.exceptions.BasicException at com.sencha.ant.AntScript.execute(AntScript.java:121)

and when i run sencha app build ios it run without any error

Answer 1

The error was so unclear in linux. But i was able to solve it. As you can see the error doesn't say anything about the head or memory but it was actually error due to small heap size. so i have to increase the memory using;

export _JAVA_OPTIONS="-Xms1024m -Xmx2048m"
