My thinking is that the Java community is most likely using CI/CD to run tests and using Maven/Gradle for that purpose, so, having support for creating the AOT cache from tests and from those tools, will allow to the community to adopt this features faster.</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">El jue, 8 may 2025 a las 21:58, <<a href="mailto:ioi.lam@oracle.com" target="_blank">ioi.lam@oracle.com</a>> escribió:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><u></u>

<p>It looks like your classpath have some directories:</p>
<p><br>
[4,648s][error ][cds ] Error: non-empty directory
'/home/danielpelaez/Documents/Distribution/aot/java-aot/build/classes/java/test'<br>

'/home/danielpelaez/Documents/Distribution/aot/java-aot/build/resources/main'</p>
<p><br>
</p>
<p>Please try to package these directories into a JAR file and use
that in your classpath.</p>

<p>Thanks</p>

<div>Hi everyone,</div>
<div><br>
</div>
<div>We are testing JEP 483 on JDK 24 using the following dummy
Gradle Spring Boot project: <a href="https://github.com/estigma88/java-aot/tree/master" target="_blank">https://github.com/estigma88/java-aot/tree/master</a>.
As we want to generate the AOT cache from the tests, we added
a custom Test task to receive the AOT flags for the JVM as
follows:</div>
<div><br>
</div>
<div>tasks.withType<Test> {<br>
useJUnitPlatform()<br>
<br>
project.findProperty("aot")?.let {<br>
val aotFlags = it.toString().split(",")<br>
jvmArgs(aotFlags)<br>
}<br>
}</div>
<div><br>
</div>
<div>And we are using the following commands to generate the AOT
cache:</div>
<div><br>
</div>
<div>./gradlew :test
-Paot="-XX:AOTMode=record,-XX:AOTConfiguration=app.aotconf"
-> This one succeed</div>
<div><br>
</div>
<div>./gradlew :test
-Paot="-XX:AOTMode=create,-XX:AOTConfiguration=app.aotconf,-XX:AOTCache=app.aot"
-> This one fails</div>
<div><br>
</div>
<div>The following are the logs for the create command:</div>
