无法在项目 oozie-client 上执行目标 org.apache.maven.plugins:maven-javadoc-plugin:2.7:javadoc (default)

Question

在构建 Apache Oozie 时，出现以下错误。

export MAVEN_OPTS="-Xmx4096m -XX:MaxPermSize=4096m"./bin/mkdistro.sh -Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2 -DskipTests -Puber -Phadoop-2 -Dhadoop.version=2.7.1 -Dhive.version=1.2.1 -Dspark.version=1.6.2

我尝试的是编辑pom.xml文件，来自

1502                     <configuration>
1503                             <additionalparam>${maven.javadoc.opts}</additionalparam>
1504                     </configuration>

至

1502                     <configuration>
1503                             <doclint>none</doclint>
1504                     </configuration>

但这没有用。

我该如何解决这个问题？

Answer 1

关于javadoc:javadoc ，名为failOnError的属性

指定如果在 javadoc 执行期间出现错误，构建是否会失败。

默认值为：真。

这会导致在创建 javadoc 期间出现任何错误时构建失败。

要忽略这一点，我们可以将插件配置如下： -

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-javadoc-plugin</artifactId>
    <version>${some-version}</version>
    <configuration>
        <failOnError>false</failOnError>
        ...
    </configuration>
</plugin>
