Question

我有两种模式：

DataRecord.avsc:
{
    "namespace": "com.mycompany",
    "type": "record",
    "name": "DataRecord",
    "fields": [
        {"name": "id", "type": ["null", "string"], "default": null},   
        {"name": "type", "type": ["null", "string"], "default": null},       
        {"name": "content", "type": ["null", "string"], "default": null},
        {"name": "error", "type": ["null", "com.mycompany.Error"], "default": null} 
    ]
}

Error.avsc:
{
    "namespace": "com.mycompany",
    "type": "error",
    "name": "Error",
    "fields": [
    ]
}

它可以与Avro 1.8.2一起使用，但是在我升级到Avro 1.9.0之后，我尝试构建时，它未能编译并生成了以下错误日志：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5:compile (default-compile) on project avro-error-type-missing-custom-coding: Compilation failure: Compilation failure:
[ERROR] /workspaces/myspace/avro-error-type-missing-custom-coding/target/generated-sources/avro/com/mycompany/DataRecord.java:[570,17] cannot find symbol
[ERROR] symbol:   method customEncode(org.apache.avro.io.Encoder)
[ERROR] location: variable error of type com.mycompany.Error
[ERROR] /workspaces/myspace/avro-error-type-missing-custom-coding/target/generated-sources/avro/com/mycompany/DataRecord.java:[608,19] cannot find symbol
[ERROR] symbol:   method customDecode(org.apache.avro.io.ResolvingDecoder)

在Avro 1.9.0中，SpecificRecordBase似乎具有customEncode()和customDecode()的方法，但是SpecificExceptionBase没有。

如何解决此问题？

Avro 1.9.0无法编译带有错误消息的生成的Java代码：找不到符号方法customEncode（org.apache.avro.io.Encoder）
