如何从源代码构建 jfreechart-1.0.19？

Question

我正在尝试构建这个项目：

git clone --depth 1 --branch v1.0.19 https://github.com/jfree/jfreechart.git

使用“mvn install”命令，出现以下错误：

Failed tests:   testFifteenMinIncludedAndExcludedSegments(org.jfree.chart.axis.SegmentedTimelineTest)
  testFifteenMinSegmentedTimeline(org.jfree.chart.axis.SegmentedTimelineTest): expected:<-2208956400000> but was:<-2208967200000>
  testMondayThroughFridaySegmentedTimeline(org.jfree.chart.axis.SegmentedTimelineTest): expected:<-2208988800000> but was:<-2208999600000>
  testFindDomainBounds(org.jfree.data.time.TimeSeriesCollectionTest): expected:<1.199142E12> but was:<1.1991348E12>

然后我尝试使用 ANT 脚本构建

cd ant
ant

我得到了 jfreechart-1.0.19-bundle.jar 8M 重量，这与 MAVEN 的 jar https://repo1.maven.org/maven2/org/jfree/jfreechart/1.0.19/ . Please tell me how to build jfreechart 版本 1.0.19 形式来源有很大不同？

Answer 1

尝试从找到的原始源代码分发中构建 here。验证校验和，解压缩文件并使用 ant:

构建

$ java -version
java version "11.0.10" 2021-01-19 LTS…
$ md5 jfreechart-1.0.19.zip 
MD5 (jfreechart-1.0.19.zip) = 69a5c88439566ac9d7e74cf34c69b7e0
$ unzip -qq jfreechart-1.0.19.zip 
$ pushd jfreechart-1.0.19
$ pushd ant ; ant ; popd
…
BUILD SUCCESSFUL

对于 lib/jfreechart-1.0.19.jar，我得到 1_565_109 字节的大小，与看到 here. You also need jcommon-1.0.23.jar, included in the lib directory and found here.

的 1_565_065 字节相当

附录：从 repository 的克隆开始，类似的方法也有效，在 lib 中生成 1_565_051 字节的 JAR和一个 8M jfreechart-1.0.19-bundle.jar:

$ git clone https://github.com/jfree/jfreechart.git jfreechart
$ pushd jfreechart
$ git fetch --tags
$ git tag --list
…
v1.0.19
…
$ git checkout v1.0.19
Note: switching to 'v1.0.19'…
$ pushd ant ; ant ; popd
…
BUILD SUCCESSFUL
$ git checkout master
$ git status
…
