我正在使用Jacoco和GEGProject的gradle进行POC，并且在“测试”任务（即测试测试源代码）中进入jacoco时遇到此错误。有任何想法吗？感谢。

test {
maxParallelForks = 5
forkEvery = 50
ignoreFailures = true
testReportDir = file("$buildDir/reports/tests/UT")
testResultsDir = file("$buildDir/test-results/UT")
//Following Jacoco test section is required only in Jenkins instance extra common file
jacoco {
//The following vars works ONLY with 1.6 of Gradle
destPath = file("$buildDir/jacoco/UT/jacocoUT.exec")
classDumpPath = file("$buildDir/jacoco/UT/classpathdumps")
//Following vars works only with versions >= 1.7 version of Gradle
//destinationFile = file("$buildDir/jacoco/UT/jacocoUT.exec")
// classDumpFile = file("$buildDir/jacoco/UT/classpathdumps")
}
}
评论以下一行，做了伎俩。我稍后会研究它，为什么它解决了这个问题。
//--- classDumpPath = file("$buildDir/jacoco/UT/classpathdumps")

我有同样的问题。帮助我的是更改JRE版本。 将其从15更改为14。
