如何向Maven Central发布Xtext 2.13项目

我已经创建了一种Xtext语言，我想将其发布到Maven central。我已经准备了以下版本：

mvn release:prepare

我第一次尝试用

mvn release:perform 

由于严格的Javadoc检查而失败（Xtext生成一些Javadoc插件无法理解的标记）。因此，我将其添加到我的

插件管理

部分，以消除错误并将其转换为警告：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-javadoc-plugin</artifactId>
    <version>2.9</version>
    <configuration>
        <additionalparam>-Xdoclint:none</additionalparam>
    </configuration>
    <executions>
        <execution>
            <id>attach-javadocs</id>
            <goals>
                <goal>jar</goal>
            </goals>
        </execution>
    </executions>
</plugin>

这一错误的原因可能是什么？如果有必要，它会在Javadoc警告之后立即发生

编辑：在手动执行Maven日志中的步骤后，我得到了完整的堆栈跟踪：

编辑2：遵循解决方案后，从-仅将tycho p2插件移动到需要它的项目-功能、存储库和目标，构建不再因

IllegalArgumentException

而中断。这次它在签名阶段失败，因为缺少名为

p2content.xml

的文件。有人知道原因是什么吗？如果我只是用

mvn clean install

构建项目，

p2content.xml

确实被创建了，所以我认为这可能是由于一些错误的执行顺序。

可能应该在调试模式下运行maven，以获得更好的错误消息发布插件在maven内部运行maven，因为它使用了存储库中的标记，因此，我无法控制构建它时使用的选项，我想您是否遵循了最初的提示我没有，但即使我现在这样做了，我仍然会得到相同的异常。我想对于edit#2，详细的错误消息也会非常有用
