[GitHub] [netbeans] pedro-w opened a new issue, #4604: Deprecation inspection does not produce any output
pedro-w opened a new issue, #4604:
URL: https://github.com/apache/netbeans/issues/4604
### Apache NetBeans version
Apache NetBeans 15 release candidate
### What happened
I wanted to find uses of deprecated API in a Java (Maven) project. But running the Inspect... item did not give any output in the Inspector window.
### How to reproduce
I have a minimal test case
``` java
public class Mavenproject2 {
public static void main(String[] args) {
Mavenproject2 it = new Mavenproject2();
System.out.println(it.test(123));
System.out.println(it.test("Hello World!"));
}
/**
* Test a number
* @param x a number
* @return another number
*/
public int test(int x) {
return x;
}
/**
* Test a String
* @param x
* @return a number
* @deprecated Use Support#test(int) instead
*/
@Deprecated()
public int test(String x) {
return x.length();
}
}
```
With this code in a maven project, select menu Source | Inspect... and choose Scope: current file and Use: single inspection deprecated. I believe this should cite use of deprecated `test(String)` in the Inspector panel but it does not.
Note the IDE does show strikethrough on both the declaration and use of that method.
### Did this work correctly in an earlier version?
No / Don't know
### Operating System
Windows 10 version 10.0 running on amd64; Cp1252; en_GB (nb)
### JDK
11.0.9.1; OpenJDK 64-Bit Server VM 11.0.9.1+1
### Apache NetBeans packaging
Apache NetBeans provided installer
### Anything else
Log file attached, as far as I can no relevant entries.

The deprecation warnings come directly from javac ([StandardJavacWarnings](https://github.com/apache/netbeans/blob/c084119009d2e0f736f225d706bc1827af283501/java/java.hints/src/org/netbeans/modules/java/hints/StandardJavacWarnings.java)). The current implementation won't work as code inspection since the hint isn't doing anything (it basically only sets compiler flags).
During the inspection, [BatchSearch](https://github.com/apache/netbeans/blob/4ae01ea70f4530443343beee3292e880a74099bd/java/spi.java.hints/src/org/netbeans/modules/java/hints/spiimpl/batch/BatchSearch.java#L603-L607) can't find anything since the pattern is null.
This applies not only for deprecations but to all other standard compiler warnings like raw types etc.
It would be fairly easy to implement a code inspection for finding usage of deprecated methods, but this wouldn't solve the other javac warnings. Would be great to find a way to fix this properly.
@jlahoda any hints? ;)
