maven-plugin-api com.thoughtworks.qdox.parser.ParseException

Question

构建项目时出现 com.thoughtworks.qdox.parser.ParseException 。这个错误首先发生在我将：更改

<packaging>jar</packaging>

为：

<packaging>maven-plugin</packaging>

之前，整个项目构建并运行干净。 maven-plugin-api 是 maven 中可用的最新版本，因此请按照“GWT、Maven、Spring - 获取 com.thoughtworks.qdox.parser.ParseException：Maven 构建上出现语法错误"行不通的。我也尝试过降级；没有变化。

例外：

有问题的类：

import javax.persistence.*;

@Table(name = "MY_TABLE")
@SecondaryTables({
        @SecondaryTable(name = "MY_TABLE2"),
        @SecondaryTable(name = "MY_TABLE3"),
        @SecondaryTable(name = "MY_TABLE4")
})
@Entity
@NamedQueries({
    ...
})
@AttributeOverrides({ // line 37
//        @AttributeOverride( //line 38
//                name = "metadataCheckOutFlag",
//                column = @Column(
//                        name = "COMMENTED_OUT_FIELD",
//                        table = "MY_TABLE2"
//                )
//        ),
})
public class MyClass extends SimpleMyClass {
}

所有 JPA 注释以前都可以正常运行。

好吧，事实证明我有另一个 Maven 插件的旧版本，maven-compiler-plugin。当我将其升级到 versino 2.3.2 时，下载了新版本的 qdox 库，即使我再次测试降级到 2.0.2 时，我的问题也消失了。 pom.xml的相关部分：

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>2.3.2</version>
        <configuration>
            <source>1.6</source>
            <target>1.6</target>
            <encoding>UTF-8</encoding>
        </configuration>
    </plugin>
