Graphviz給出了很多字體錯誤

Question

我正在使用maven和maven-javadoc插件與umlgraph-doclet來爲我的項目創建javadoc。該部分從我的POM：

<build> 
    <plugins> 
    <plugin> 
     <groupId>org.apache.maven.plugins</groupId> 
     <artifactId>maven-site-plugin</artifactId> 
     <inherited>false</inherited> 
     <configuration> 
     <reportPlugins> 
      <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-javadoc-plugin</artifactId> 
      <version>2.8</version> 
      <configuration> 
       <show>public</show> 
       <quiet>true</quiet> 

       <doclet>org.umlgraph.doclet.UmlGraphDoc</doclet>

      </plugin> 
     </reportPlugins> 
     </configuration> 
    </plugin> 
    </plugins> 
</build> 

這些是我使用由umlgraph的doclet生成的.dot文件運行mvn site或可替代dot -Tpng class.dot -o class.cli.png時，你得到的錯誤：在該列表中

[0] Times-Roman => "Times, REGULAR" 
[1] Times-Italic => "Times, REGULAR ITALIC" 
[2] Times-Bold => "Times, BOLD" 
[3] Times-BoldItalic => "Times, BOLD ITALIC" 
[4] AvantGarde-Book => "URW Gothic L, BOOK"

[26] NewCenturySchlbk-Bold => "Century Schoolbook L, BOLD" 
[27] NewCenturySchlbk-BoldItalic => "Century Schoolbook L, BOLD ITALIC" 
[28] Palatino-Roman => "URW Palladio L, ROMAN" 
[29] Palatino-Italic => "URW Palladio L, REGULAR ITALIC" 
[30] Palatino-Bold => "URW Palladio L, BOLD"

[32] Symbol => "Impact, " 
[33] ZapfChancery-MediumItalic => "URW Chancery L, ITALIC" 
[34] ZapfDingbats => "Dingbats, REGULAR" 

並非所有的字體在.dot文件中使用，只有Helvetica在那裏使用。我正在使用Linux。我可以爲您提供用於測試的.dot文件。 我的另一個觀察：在終端中運行時，不是每次運行都會顯示這些錯誤。每三場比賽平均水平沒有他們。輸出時運行與-v：

任何人都知道如何解決或抑制它們？它討厭每一代網站都要克服這些錯誤的2k行。

Answer 1

不幸的是，因爲點的命令行選項在UmlGraphDoc.java硬編碼的，有改變點的命令行選項[可以創建與需要的參數實際點之前進來的路徑shell腳本命名點]

代碼沒有直接的方法片段UmlGraphDoc.java

p = Runtime.getRuntime().exec(
    new String[] { "dot", "-Tcmapx", "-o", 
    mapFile.getAbsolutePath(), "-Tpng", "-o", 
    pngFile.getAbsolutePath(), 
    dotFile.getAbsolutePath() }); 

<quiet>true</quiet>選項maven-javadoc-plugin不抑制警告和錯誤

AFAIK唯一的辦法左邊是要麼

在安靜模式下運行Maven

mvn -q 

還是要grep行家命令的輸出，以抑制含=>

mvn site | grep -v ' => "' 

Answer 2

您看到的消息是調試腳手架的一部分。它們不是錯誤，而是關於字體映射的信息。這僅在Graphviz在-v值爲2或更大的情況下運行時纔會打印。相關的內部代碼是

if (Verbose > 1) 
    printFontMap (gv_fmap, ps_fontnames_sz); 

這應該是完全確定性的。我需要更多關於Graphviz如何被maven用來建議更多細節的信息。
