Travis created NETBEANS-2346:
--------------------------------
Summary: Netbeans throws ArrayIndexOutOfBoundsException when
opening Gradle projects containing unversioned dependencies
Key: NETBEANS-2346
URL: https://issues.apache.org/jira/browse/NETBEANS-2346
Project: NetBeans
Issue Type: Bug
Components: projects - Gradle
Affects Versions: 11.0
Reporter: Travis
Assignee: Laszlo Kishalmi
I am trying to load a project that uses local .jar file dependencies. The
build.gradle contains something like:
repositories {
flatDir dirs: [ "$rootDir/lib" ]
}
dependencies {
testImplementation name: 'hamcrest-core-1.3'
}
And there is a file hamcrest-core-1.3.jar in the project's "lib" folder.
This all works fine with Netbeans versions prior to 11 (using the third-party
Gradle plugin, of course).
But when Netbeans 11 vc4 loads the same project, it throws the following
exception:
java.lang.ArrayIndexOutOfBoundsException: Index 2 out of bounds for length 2

I took a look in GradleDependency.java line 85 and found:
ModuleDependency(String id, Set<File> artifacts) {
super(id);
this.artifacts = artifacts;
String[] parts = id.split(":");
group = parts[0];
name = parts[1];
version = parts[2];
}
That code appears to be making the blind assumption that all dependencies will
have all three parts: group, name, version. But it is possible and legal to
specify only name for local .jar dependencies like mine.
After this exception, the "Source Packages" subtree is completely missing from
the "Projects" pane. Although the project load gracefully recovers and some
operations still work on the project, the IDE is effectively unusuable without
the ability to browse packages and classes.
I found a simple workaround, which is to rewrite the same dependencies in
build.gradle to use the full group:name:version format, with fake group and
version values just to make Netbeans happy:
testImplementation 'dummy:hamcrest-core-1.3:dummy'
With that workaround, Netbeans 11 works much better.
Although that workaround is acceptable, it results in otherwise unnecessary
clutter in the build.gradle files, so I'm hoping to revert it after a future
Netbeans update.
Please fix the Netbeans Gradle support to properly handle name-only
dependencies like the example above. Thank you!
By the way, I don't know if it makes any difference here, but I'm using:
Windows 10
Netbeans 11 vc4
Gradle 5.2
Java 12
Gradle Plugin 2.0.2
Yes, I'm trying to keep using the old plugin, but the new Gradle built-in
support still interferes in this manner, despite showing up as disabled in the
Plugins browser. Apparently some of the built-in code still runs even in that
scenario?
If it would help for me to provide an example tiny project to demonstrate this
bug, I could provide one on GitHub... just let me know if that would help.
