gradle - 使用Cobertura会产生NoClassDefFoundError

Question

我们正在使用Cobertura(在gradle构建中定义)。当我部署应用程序并在swing客户端中单击时，出现了来自cobertura的NoClassDefFoundError。

java.lang.NoClassDefFoundError: net/sourceforge/cobertura/coveragedata/HasBeenInstrumented

我不知道这是从哪里来的。在我的Java代码中，cobertura没有任何内容。定义cobertura的唯一地方是在gradle构建文件中作为依赖项:

testCompile "net.sourceforge.cobertura:cobertura:1.9.4.1"

我对两个主要项目做了一个总结:

find -type f -name "*gradle*" -exec grep -Hn cobertura {} \;

结果如下:

./BigTableDataProvider/ext-test/build.gradle:7:def cobSerFile = "$buildDir/cobertura.ser"
./BigTableDataProvider/ext-test/build.gradle:24:    testCompile 'net.sourceforge.cobertura:cobertura:1.9.4.1'
./BigTableDataProvider/ext-test/build.gradle:34:    codeCoverageRun 'net.sourceforge.cobertura:cobertura:1.9.4.1'
./BigTableDataProvider/ext-test/build.gradle:42:    jvmArgs = sampleJvmArg.split(" ").toList() << "-Dnet.sourceforge.cobertura.datafile=$cobSerFile"
./BigTableDataProvider/ext-test/build.gradle:50:        'cobertura-instrument'(datafile: cobSerFile) {
./BigTableDataProvider/ext-test/build.gradle:63:    ant.'cobertura-report'(destdir: "${project.buildDirName}/reports/codeCoverage",

./BigTableExplorer/sample/server/build.gradle:10:    testCompile 'net.sourceforge.cobertura:cobertura:1.9.4.1' // Add this if sample module has inherited classes from server.
./BigTableExplorer/ext-server/build.gradle:20:    testCompile "net.sourceforge.cobertura:cobertura:1.9.4.1"
./BigTableExplorer/ext-test/build.gradle:7:def cobSerFile = "cobertura.ser"
./BigTableExplorer/ext-test/build.gradle:22:    testCompile 'net.sourceforge.cobertura:cobertura:1.9.4.1'
./BigTableExplorer/ext-test/build.gradle:34:    codeCoverageRun 'net.sourceforge.cobertura:cobertura:1.9.4.1'
./BigTableExplorer/ext-test/build.gradle:42:    jvmArgs = sampleJvmArg.split(" ").toList() << "-Dnet.sourceforge.cobertura.datafile=$cobSerFile"
./BigTableExplorer/ext-test/build.gradle:50:        'cobertura-instrument'(datafile: cobSerFile) {
./BigTableExplorer/ext-test/build.gradle:63:    ant.'cobertura-report'(destdir: "${project.buildDirName}/reports/codeCoverage",

您不小心部署了Cobertura测试的代码。 Gradle构建必须使用某些第三方Cobertura插件或Cobertura Ant任务，并且显然配置不正确。
