Is there a way to increase the size of my MATERIAL Font.Image icons on my Toolbar?
Since our app is aimed at tablets and the desktop, I need to increase the back arrow and check mark on my toolbar.

Do I still need the cn1libs listing in my Codename One Project?
I have created a fresh CN1 Project, updated the pom file to 7.0.156, and rebuilt the project. The pom has a “Cannot resolve symbol ‘cn1libs'” error at module cn1libs. I tried to install the cn1libs using the maven cn1:installcn1libs and got Failed to execute goal com.codenameone:codenameone-maven-plugin:7.0.156:installcn1libs (default-cli) on project taapp-javase: Execution default-cli of goal com.codenameone:codenameone-maven-plugin:7.0.156:installcn1libs failed. Do I still need the reference to the cn1libs, and if so, how do I get past this issue? Also, the build has a failure “CSS> SLF4J: Failed to load class “org.slf4j.impl.StaticLoggerBinder””. Do I need to manually load the slf4j file for the css? The simulator runs the Hello World app correctly. Thanks.

Does anyone have any idea on the steps to repair the pom and complete the Maven rebuild?

Having trouble connecting to my database in Codename One
I have been fighting to copy my included SQLite database to FileSystemStorage, but I finally succeeded.
