commit 9f8e62e35399a8bd2156dec39d9a8696d4264eb5 Author: GitHub Copilot <[email protected]> AuthorDate: Fri Dec 26 09:28:42 2025 +0000 Add PATH fallback when JAVA_HOME is unset - Modified AbstractJDepsMojo.getJDepsExecutable() to search for jdeps in PATH when JAVA_HOME is not set or jdeps is not found in JAVA_HOME - Changed JAVA_HOME from required to optional - Improved error message to inform users about both JAVA_HOME and PATH options - Added integration test to verify PATH fallback functionality works correctly This change allows the plugin to work in environments where JAVA_HOME is not set, as long as jdeps is available in the system PATH, which is common in many development environments and CI/CD systems. Fixes: Support for running jdeps when JAVA_HOME is not configured --- src/it/path-fallback/invoker.properties | 19 ++++++++ src/it/path-fallback/pom.xml | 55 ++++++++++++++++++++++ src/it/path-fallback/src/main/java/Main.java | 24 ++++++++++ src/it/path-fallback/verify.groovy | 32 +++++++++++++ .../maven/plugins/jdeps/AbstractJDepsMojo.java | 37 ++++++++++----- 5 files changed, 156 insertions(+), 11 deletions(-) diff --git a/src/it/path-fallback/invoker.properties b/src/it/path-fallback/invoker.properties new file mode 100644 index 0000000..e998805 --- /dev/null +++ b/src/it/path-fallback/invoker.properties @@ -0,0 +1,19 @@ +# Licensed to the Apache Software Foundation (ASF) under one +# or more contributor license agreements.
