---------------------------------------
Summary: nb-javac "Compile on Save" causes "cannot find symbol"
for types that are present
Key: NETBEANS-5539
URL: https://issues.apache.org/jira/browse/NETBEANS-5539
Project: NetBeans
Issue Type: Bug
Affects Versions: 12.3
Environment: *Product Version:* Apache NetBeans IDE 12.3
*Java:* 11.0.10; OpenJDK 64-Bit Server VM 11.0.10+9-Ubuntu-0ubuntu1.20.04
*Runtime:* OpenJDK Runtime Environment 11.0.10+9-Ubuntu-0ubuntu1.20.04
*System:* Linux version 5.4.0-70-generic running on amd64; UTF-8; de_DE (nb)
Reporter: Torsten Römer
Attachments: VaultTranscriberTest.png, netbeans-test.tar.gz
*What I did:*
# Clean install of NetBeans 12.3
# Installed nb-javac as recommended, restarted NetBeans
# Cloned [https://github.com/keycloak/keycloak.git] (13.0.0-SNAPSHOT) from
within NetBeans
# Opened the parent project
# Did "Clean and Build" of the whole project (success)
# Expanded "Modules", all looks fine
# Opened module "Keycloak REST Services": "Background scanning of projects..."
takes a long time and there are constantly occurring "Unexpected Exception"
(some NPE but it is impossible to select one because they are being replaced by
a new occurrence all the time)
# Opened the attached project "netbeans-test"
*Expected behaviour:*
* All projects open without error
*Observed behaviour:*
* When opening the module "Keycloak REST Services" is complete, there are
several "cannot find symbol" errors for types that are actually present, for
example DefaultVaultTranscriber in VaultTranscriberTest (see screenshot)
* In the project "netbeans-test", in NetBeansTest.java, the import
org.keycloak.crypto.ES256SignatureProviderFactory as well has "cannot find
symbol" and content-assist for the package org.keycloak.crypto only shows a
subset of the types that actually are in the package
*Workaround:*
Disabling "Compile on Save", deleting the cache in ~/.cache/netbeans,
rebuilding the project, restarting NetBeans etc. does not solve the issue.
"Uninstalling" nb-javac by deleting ~/.netbeans/12.3/modules and restarting
NetBeans solves the problem, but then of course "Compile on Save" with all its
advantages is not available any more.
Then nb-javac can be installed and "Compile on Save" enabled again - no errors
show up (but might occur again later?)
*Additional information:*
In NetBeans 12.4 Beta 1 "Compile on Save" can be enabled *without installing
nb-javac*, and when running a test or debugging, the following message shows up:
{{Running NetBeans Compile On Save execution. Phase execution is skipped and
output directories of dependency projects (with Compile on Save turned on) will
be used instead of their jar artifacts.}}
And it works just fine - "Compile on Save" is available without nb-javac in
12.4 Beta 1?
