自从我使用 Maven 以来，我已经能够在我的本地存储库中构建和安装具有不完整 Javadoc 标记(例如，缺少参数)的项目。

然而，自从我迁移到 Java 8 (1.8.0-ea-b90) 之后，当我尝试构建或安装一个项目Javadoc 不是“完美的”。我尝试在本地存储库中编译和安装的一些项目是我无法控制的第三方项目。因此，在我的场景中，仅修复所有这些项目中的所有 Javadocs 的解决方法似乎并不可行。

这是我执行 mvn clean package install 时看到的一小部分输出在我的项目中:

Javadoc Maven 插件在我的 POM 中是这样配置的:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-javadoc-plugin</artifactId>
    <version>2.9</version>
    <executions>
        <execution>
            <id>attach-javadocs</id>
            <goals>
                <goal>jar</goal>
            </goals>
        </execution>
    </executions>
</plugin>

正如我之前所说，如果我回到 Java 7，一切都会正常工作。 也许这是与在 Java 8 中运行的 Maven 相关的错误？ 如何使用 Java 8 使其工作(即能够构建项目的 Javadoc 并将其代码安装在我的本地存储库中)？ 我已经在 OSX 中使用 Maven 3.0.3 和 3.0.5 进行了测试。

更新:

如果我用 <failOnError>false</failOnError> 更改我的 Javadoc 插件配置(感谢马丁):

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-javadoc-plugin</artifactId>
    <version>2.9</version>
    <executions>
        <execution>
            <id>attach-javadocs</id>
            <goals>
                <goal>jar</goal>
            </goals>
        </execution>
    </executions>
</plugin>

然后该项目安装在我的本地存储库中。但是，仍然没有生成 Javadoc JAR。

我在控制台中看到的带有这个新配置的输出片段是:

[ERROR] MavenReportException: Error while creating archive: Exit code: 1 - /Users/....java:18: warning: no @param ... Command line was: /Library/Java/Home/bin/javadoc @options @packages

在使用 Java 7 时，关于如何一步构建源代码、安装项目和生成 Javadoc JAR 的任何解决方法？

最佳答案

最好的解决方案是修复 javadoc 错误。如果由于某种原因不可能(即:自动生成的源代码)，那么您可以禁用此检查。

DocLint is a new feature in Java 8 ，总结为:

Provide a means to detect errors in Javadoc comments early in the development cycle and in a way that is easily linked back to the source code.

这是默认启用的，并且会在生成 Javadocs 之前运行大量检查。您需要按照指定 in this thread 为 Java 8 关闭此功能。 .您必须将其添加到您的 Maven 配置中:

<profiles>
  <profile>
    <id>java8-doclint-disabled</id>
    <activation>
      <jdk>[1.8,)</jdk>
    </activation>
    <properties>
      <javadoc.opts>-Xdoclint:none</javadoc.opts>
    </properties>
  </profile>
</profiles>
<build>
  <plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-javadoc-plugin</artifactId>
        <version>2.9</version>
        <executions>
            <execution>
                <id>attach-javadocs</id>
                <goals>
                    <goal>jar</goal>
                </goals>
                <configuration>
                    <additionalparam>${javadoc.opts}</additionalparam>
                </configuration>
            </execution>
        </executions>
    </plugin>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-site-plugin</artifactId>
        <version>3.3</version>
        <configuration>
          <reportPlugins>
            <plugin>
              <groupId>org.apache.maven.plugins</groupId>
              <artifactId>maven-javadoc-plugin</artifactId>
              <configuration>
                <additionalparam>${javadoc.opts}</additionalparam>
              </configuration>
            </plugin>
          </reportPlugins>
        </configuration>
      </plugin>
   </plugins>
</build>

对于 maven-javadoc-plugin 3.0.0+: 替换

<additionalparam>-Xdoclint:none</additionalparam>

与

<doclint>none</doclint>
