JAXB2 由于'[..]ToStringStrategy cannot be converted to [..]ToStringStrategy2'，无法为 XSD 生成类

Question

我在0.12.0版本中将maven-jaxb2-plugin与org.jvnet.jaxb2_commons.jaxb2-basics一起使用时发现了toString生成的问题。它没有生成 JAXBToStringStrategy.INSTANCE2，而是使用与 ToStringStrategy2 不兼容的 INSTANCE，如下所示：

public String toString() {
final ToStringStrategy2 strategy = JAXBToStringStrategy.INSTANCE;
final StringBuilder buffer = new StringBuilder();
append(null, buffer, strategy);
return buffer.toString();
}

因此，maven 构建在编译时失败，并出现以下示例错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project test: Compilation failure
[ERROR] /D:/test/jaxb2/target/generated-sources/xjc/xsd/file/File.java:[73,64] incompatible types: org.jvnet.jaxb2_commons.lang.ToStringStrategy cannot be converted to org.jvnet.jaxb2_commons.lang.ToStringStrategy2

出于某种原因，当我对org.jvnet.jax-ws-commons.jaxws-maven-plugin使用相同的配置从WSDL生成类时，使用了正确的INSTANCE2。我还尝试通过以下方式显式给出使用哪个类：

-XtoString-toStringBuilder=org.jvnet.jaxb2_commons.lang.JAXBToStringStrategy

或

-XtoString-toStringStrategyClass=org.jvnet.jaxb2_commons.lang.JAXBToStringStrategy

但没有任何改变。有人有类似的问题吗？示例如下：

XSD [应放在pom旁边]：

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema 
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:file="file.xsd"
targetNamespace="file.xsd"
elementFormDefault="qualified">
<xsd:element name="file">
<xsd:complexType>
<xsd:attribute name="id" type="xsd:string" use="optional"/>
</xsd:complexType>
</xsd:element>
</xsd:schema>

尝试对 jaxb2-basics 和 jaxb2-basics-runtime 使用版本 "1.11.1" 而不是 "0.12.0">
