-----------------------------------------
Summary: Add Xpkginfo:always to Compiler Args
Key: IGNITE-21057
URL: https://issues.apache.org/jira/browse/IGNITE-21057
Project: Ignite
Issue Type: Wish
Components: build
Affects Versions: 2.15
Reporter: Jonathan Strauss
From: [javac
manual|[https://docs.oracle.com/en/java/javase/17/docs/specs/man/javac.html]]

-Xpkginfo:[always, legacy, nonempty]
Specifies when and how the javac command generates package-info.class files
from package-info.java files using one of the following options:
always
Generates a package-info.class file for every package-info.java file. This
option may be useful if you use a build system such as Ant, which checks that
each .java file has a corresponding .class file.
legacy
Generates a package-info.class file only if package-info.java contains
annotations. This option does not generate a package-info.class file if
package-info.java contains only comments.
Note: A package-info.class file might be generated but be empty if all the
annotations in the package-info.java file have RetentionPolicy.SOURCE.
nonempty
Generates a package-info.class file only if package-info.java contains
annotations with RetentionPolicy.CLASS or RetentionPolicy.RUNTIME.
{noformat}
The Maven Compiler plugin will always recompile the entire project because
there are a number of package-info.java source files with no corresponding
package-info.class files, adding:
{code:java}
<compilerArgs>
<arg>-Xpkginfo:always</arg>
....{code}
Forces the compilation of these Java source files thereby allowing the build
cache to function properly.
