From 6255394ecca5eaf6bbb21413430029cbd3ef1088 Mon Sep 17 00:00:00 2001 From: Guillaume Nodet Date: Mon, 8 Sep 2025 17:13:51 +0200 Subject: [PATCH] Fix mvnd.java.home not set in noDaemon mode (#1410) Fixes #1248 When running with mvnd.noDaemon=true, the connectNoDaemon() method was setting up various system properties but missing the crucial MVND_JAVA_HOME property. This caused the Server constructor to fail with 'The system property mvnd.java.home is missing'. The fix adds the missing MVND_JAVA_HOME property in connectNoDaemon() using the same value as JAVA_HOME from parameters.javaHome(). Changes: - Add MVND_JAVA_HOME property setup in DaemonConnector.connectNoDaemon() - Add NoDaemonTest to verify the fix works correctly The solution follows the existing pattern used for other properties in the same method and ensures noDaemon mode works as expected. --- .../mvnd/client/DaemonConnector.java | 2 + .../mvndaemon/mvnd/client/NoDaemonTest.java | 137 ++++++++++++++++++ 2 files changed, 139 insertions(+) create mode 100644 client/src/test/java/org/mvndaemon/mvnd/client/NoDaemonTest.java diff --git a/client/src/main/java/org/mvndaemon/mvnd/client/DaemonConnector.java b/client/src/main/java/org/mvndaemon/mvnd/client/DaemonConnector.java index 454346c8..1302f655 100644 --- a/client/src/main/java/org/mvndaemon/mvnd/client/DaemonConnector.java +++ b/client/src/main/java/org/mvndaemon/mvnd/client/DaemonConnector.java @@ -143,6 +143,8 @@ public class DaemonConnector { parameters.daemonStorage().toString()); properties.put( Environment.MVND_REGISTRY.getProperty(), parameters.registry().toString()); + properties.put( + Environment.MVND_JAVA_HOME.getProperty(), parameters.javaHome().toString()); properties.putAll(parameters.getDaemonOptsMap()); Environment.setProperties(properties); AtomicReference throwable = new AtomicReference<>(); diff --git a/client/src/test/java/org/mvndaemon/mvnd/client/NoDaemonTest.java b/client/src/test/java/org/mvndaemon/mvnd/client/NoDaemonTest.java new file mode 100644 index 00000000..a4a3b6fa --- /dev/null +++ b/client/src/test/java/org/mvndaemon/mvnd/client/NoDaemonTest.java @@ -0,0 +1,137 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.
