I found that the logic of the ifAllResourcesPresent and ifAnyResourcesPresent methods is exactly the same https://github.com/spring-projects/spring-boot/blob/master/spring-boot-project/spring-boot-cli/src/main/java/org/springframework/boot/cli/compiler/DependencyCustomizer.java#L131

`

/**
 * Create a nested {@link DependencyCustomizer} that only applies if the specified
 * paths are on the class path.
 * @param paths the paths to test
 * @return a nested {@link DependencyCustomizer}
 */
public DependencyCustomizer ifAllResourcesPresent(String... paths) {
    return new DependencyCustomizer(this) {
        @Override
        protected boolean canAdd() {
            for (String path : paths) {
                try {
                    return DependencyCustomizer.this.loader.getResource(path) != null;
                }
                catch (Exception ex) {
                    // swallow exception and continue
                }
            }
            return DependencyCustomizer.this.canAdd();
        }
    };
}

    return new DependencyCustomizer(this) {

Thanks for the report. Have you written a CLI extension where this is causing a problem? As far as I can tell, Spring Boot itself doesn't use ifAllResourcesPresent.

Thanks for the reply, I did not cause a specific problem because of the ifAllResourcesPresent method, I just found it in the process of reading the source code
