@copilot Nein daran liegt es nicht. Kotlin wird durch das plugin surf-api bereitgestellt und spring durch das plugin surf-cloud. Es ging ja auch wie gesagt erst nicht mehr nachdem ich den openai client hinzugefügt habe 22:22:22 INFO]: Current classloader: PaperPluginClassLoader{libraryLoader=io.papermc.paper.plugin.entrypoint.classloader.BytecodeModifyingURLClassLoader@9294b14, seenIllegalAccess=[], loadedJavaPlugin=surf-chat-paper v1.21.10-4.1.5-SNAPSHOT} |

You're absolutely right! The issue is not with the Kotlin metadata exclusion. The real problem is a Jackson relocation conflict caused by the OpenAI client. The ShadowJar relocates Jackson to Fixed in commit f348e79 by excluding Jackson from the OpenAI dependency so it uses the relocated Jackson provided by surf-cloud: implementation("com.openai:openai-java:4.11.0") {
// ... existing exclusions ...
exclude(group = "com.fasterxml.jackson.core")
exclude(group = "com.fasterxml.jackson.databind")
exclude(group = "com.fasterxml.jackson.datatype")
exclude(group = "com.fasterxml.jackson.module")
}See |

The Jackson exclusion broke the OpenAI client because it needs Jackson to deserialize JSON responses. Root cause: The Jackson relocation in Fixed in commit 201497e by removing the Jackson relocation entirely: // REMOVED from surf-chat-paper/build.gradle.kts:
tasks.shadowJar {
relocate("com.fasterxml.jackson", "dev.slne.surf.chat.shadow.jackson")
}There's no actual conflict - both OpenAI and Spring can share Jackson from surf-cloud. The relocation was unnecessary and created the problem. See |

@copilot Das bringt halt auch nur so halb was, also spring scannt die klassen jetzt wieder, aber es gibt jetzt das problem hier: Wahrscheinlich weil unterschiedliche fasterxml versionen benitzt werden [22:52:37 ERROR]: [surf-chat-paper] This is not an error of MCCoroutine! See sub exception for details. |

You're correct - there's a Jackson version conflict. OpenAI client requires Jackson 2.18+ (which has Fixed in commit 9993285 by forcing all Jackson dependencies to version 2.18.2: // In surf-chat-core-common/build.gradle.kts
configurations.all {
resolutionStrategy.eachDependency {
if (requested.group.startsWith("com.fasterxml.jackson")) {
useVersion("2.18.2")
because("OpenAI client requires Jackson 2.18+ for OptBoolean support")
}
}
}This aligns all Jackson modules to the same version, preventing the |

The previous fix only applied to the submodule level. Since surf-cloud provides Jackson through a plugin, the version forcing needs to be at the root level. Fixed in commit c89e77a by applying Jackson version forcing in root allprojects {
configurations.configureEach {
resolutionStrategy.eachDependency {
if (requested.group.startsWith("com.fasterxml.jackson")) {
useVersion("2.18.2")
because("OpenAI client requires Jackson 2.18+ for OptBoolean support")
}
}
}
}This ensures ALL modules including plugin-provided dependencies use Jackson 2.18.2. |

Spring successfully initializes but skips all user beans (
@Service,@Component) fromdev.slne.*packages, causingNoSuchBeanDefinitionException. Only auto-configuration beans are registered.Root Cause
The issue is caused by a Jackson version conflict between the OpenAI client and surf-cloud:
com.openai:openai-java:4.11.0) requires Jackson 2.18+, which introducedOptBooleanas the return type forJsonProperty.isRequired()JsonProperty.isRequired()returnsbooleanNoSuchMethodError: 'com.fasterxml.jackson.annotation.OptBoolean com.fasterxml.jackson.annotation.JsonProperty.isRequired()'The Jackson relocation in ShadowJar configuration compounded the issue by preventing the OpenAI client from finding Jackson classes, but the underlying problem was the version mismatch.
Changes
Three fixes were required:
surf-chat-paper/build.gradle.kts: Removed unnecessary Jackson relocationsurf-chat-core/surf-chat-core-common/build.gradle.kts: Added Jackson version alignment at submodule levelbuild.gradle.kts: Added Jackson version alignment at root level (critical for plugin-provided dependencies)allprojects { configurations.configureEach { resolutionStrategy.eachDependency { if (requested.group.startsWith("com.fasterxml.jackson")) { useVersion("2.18.2") because("OpenAI client requires Jackson 2.18+ for OptBoolean support") } } } }JACKSON_VERSION_CONFLICT_FIX.md: Comprehensive technical documentation covering:Why Root-Level Forcing is Critical
The key discovery was that Gradle plugin-provided dependencies bypass submodule-level resolution strategies:
surf-cloudprovides Jackson through a Gradle plugin (withCloudClientPaper())resolutionStrategydoesn't affect plugin-provided dependenciesallprojectsblock withconfigurations.configureEachensures all modules (including those configured by plugins) use the same Jackson versionWhy This Works
OptBooleanAPI that jackson-module-kotlin expectsWhy Silent Failure Occurred
Spring's component scanner gracefully handles errors by logging at DEBUG level and continuing to scan other classes. When beans fail to load due to
NoSuchMethodError, Spring simply skips them without throwing exceptions during startup. TheNoSuchBeanDefinitionExceptiononly appears later when code attempts to inject the missing beans.Technical Details
Jackson 2.18 introduced a breaking change in the
JsonPropertyinterface:This method signature change breaks binary compatibility at runtime, causing
NoSuchMethodErrorwhen jackson-module-kotlin tries to call the method expectingOptBooleanbut finds the oldbooleanreturn type.Original prompt
