Java 错误："；复制源文件<；未知>&引用；

我正在学校管理的共享服务器上进行Jenkins项目。我的

build.xml

文件具有以下FindBugs执行的相关步骤：

<target name="findbugs">
    <echo>FindBugs Starting:</echo>

    <available file="${findbugs.dir}/findbugs.jar" property="findbugs.available" />
    <fail unless="findbugs.available" message="Error: FINDBUGS_HOME not set or findbugs.jar not found." />

    <taskdef name="findbugs" classname="edu.umd.cs.findbugs.anttask.FindBugsTask" classpath="${findbugs.dir}/findbugs-ant.jar" />
    <findbugs home="${findbugs.dir}"
        workHard="true"
        output="xml:withMessages"
        outputFile="${report.dir}/findbugs.xml"
        excludefilter="findbugs-exclusions.xml"
        sourcePath="${src.dir}" >
        <class location="${classes.dir}" />
        <auxClasspath>
            <fileset file="${lib.dir}/junit.jar" />
        </auxClasspath>
     </findbugs>

    <echo>FindBugs finished</echo>
</target>

在“文件”选项卡下的FindBugs警告结果中，列出了一个名为“”的文件，在该详细信息中，我看到了以下内容：

com.ewenicorn.reddit.dailyprogrammer.utility.CharacterUtilityTest.testShiftCharacter（）调用无效的新字符（char）构造函数；改为使用Character.valueOf（char）

我正在寻找解决这个错误，所以任何可用的帮助都是非常感谢的，特别是因为我还没有从以前研究这个问题的人那里找到任何东西。如果需要额外的结构，可以在中找到该文件的完整源代码和二进制文件，并且对于使用Ant的构建来说，它应该是开箱即用的。

“未知源文件”很可能是因为在编译代码时没有调试信息

我为您的git项目创建了一个jenkins freestyle作业，添加了一个目标为“main”的ant构建，添加了一个findbugs构建后操作，jenkins（1.525）生成了findbugs图。我还有“com.ewenicorn.reddit.dailyprogrammer.utility-File”文件，但它不会产生问题。您是否可以指定：您的jenkins版本、使用的findbugs版本、您的平台，无论您是否使用分布式构建。注意：我必须编辑src/com/ewenicorn/reddit/dailyprogrammer/intermediate/complete/Problem011UpsideUpNumbers.java，因为它包含非UTF-8字符。感谢开始-我同意Problem011UpsideUpNumbers.java有问题，我现在将它作为一个问题的示例保留在那里，以便稍后更正（这是项目的一部分，不应该影响到这一点）。无论如何，我正在使用FindBugs 4.50开发Jenkins 1.528，理论上是在RedHat或同等发行版上（虽然我看不到，但我肯定有*NIX-like路径）。实际上，我升级到了最新的Jenkins+插件，以避免版本问题。这也是一项自由式的工作，没有什么特别之处。我在结果中看到了1个列出的“警告”，这是我关心的问题。我也有同样的问题，在谷歌上搜索了很多次，没有找到答案。但是，我发现如果你点击“警告”链接到左列，而不是单击图表，然后单击“新建”tab然后你可以深入到代码中。这是唯一对我有效的方法。你能确认它是否对你有效吗？谢谢。可能是这个问题无效。问题不在于复制。我检查了findbugs_report.xml以了解我也会遇到这种情况的情况。它包含以下行：，这意味着Jenkins可以只会失败。
