Jean-François El Fouly updated NETBEANS-19:
-------------------------------------------
Description:
An annoying and tricky little bug.
h1. Nominal scenario (NetBeans non-Maven project)
# File > New Project...
# Java | Java application (You could uncheck Create Main Class)
# New > JFrame Form...
# In the designer drag a JLabel
# For the icon property click "..."
# Click Import to Project...
# Choose an icon then Finish
# The icon is copied along the java source file
# Run
# Everybody happy. It works
h1. Maven project
# File > New Project...
# Maven | Java application
# New > JFrame Form... (Default values OK)
# In the designer drag a JLabel
# For the icon property click "..."
# Click Import to Project...
# Choose an icon then Finish
# The icon is copied along the java source file
# Run
# It crashes with a NullPointerException
h2. Manual remediation
# In the project create src/main/resources
# Move the icon to this directory (same package as it was under src/main/java)
# NetBeans detects this and adds "Other Sources" to the project tree
# mvn clean (to force rebuild)
# Now it works
h1. Rationale
Importing an icon and associating to a JLabel generates code such as this:
bq. jLabel1.setIcon(new
javax.swing.ImageIcon(getClass().getResource("/test/mavenproject1/bookmark.png")));
// NOI18N
But the maven compiler plugin will not copy the icon to target/classes so
target/classes contains the classes but not the image. So the code above causes
a NPE.
h2.Bottom line
In a Maven project icons should not be imported to src/main/java but to
src/main/resources, same package.
This small but annoying bug is not a regression: it can easily be reproduced in
8.2
