Question

在Jenkins构建我们的多模块maven 3项目时，如果出现构建错误，我们会收到maven编译器插件失败的神秘消息。这才刚刚开始在上周发生：

从命令行构建时，我们得到正常的构建错误：

我们在本地版本和Jenkins上都使用maven-3.0.4。詹金斯版本是1.3ish，但我升级到1.450，看看问题是否会消失 - 事实并非如此。这发生在我们从maven-2.2.1移动到maven-3.0.4的时候，但是我可以发誓（虽然我没有证据）我在Jenven升级之后就得到了正常的构建错误，所以我不要以为就是这样，但这是我能想到的唯一一个会导致这种变化的变化。编译器插件版本是2.0.2。

我看到了一个类似的帖子here，但他的问题与eclipse构建有关，而不是Jenkins。

Answer 1

我使用的maven编译器插件版本是2.3.2。从下面的输出中可以看出我遇到了错误。

插件的pom配置是

            <!-- Compiler Version to use for Compiling Java Code -->
            <plugin>
                <inherited>true</inherited>
                <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>
                </configuration>
            </plugin>

没有其他特殊配置。我正在使用Hudson 2.2.0-BETA和Hudson :: Maven（遗留）插件2.2.0-BETA。

Answer 2

不确定这是否能解决您的问题，但我遇到了完全相同的问题，因为父pom有编译器插件的插件定义。我将相同的插件定义复制到实际的项目pom中。这解决了我的问题，即Jenkins现在正确显示编译器错误。不知道为什么这解决了问题，但确实如此。也许它与maven分配进程来编译子模块这一事实有关，而且该终端没有通过管道连接到jenkins控制台。我有空的时候会去探索更多。

如果这对您有用，请告诉我。我已将我的插件定义复制到其相当标准的下方：

<plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>2.5.1</version>
        <configuration>
            <source>1.6</source>
            <target>1.6</target>
        </configuration>
    </plugin>
</plugins>

Answer 3

您应该检查ActivityRuntimeType类的位置。很可能它不在编译器的构建或类路径上。当您依赖的类处于意外更改的依赖项中时，通常会发生这种情况。

Jenkins没有显示maven编译器错误
